What's new in MODO 17.0v2

Mar 22, 2024

Experience new levels of performance and unlock your creative potential with the new Modo 17.0. With an overhauled architecture and powerful tool performance enhancements, Modo just got even better.
Mesh View Objects:
This is the largest architectural change Modo has ever seen. We’ve created a system that allows us to accelerate how quickly things are drawn in the viewport and added the ability to push a calculation to a background thread. This means that Modo can leverage two threads at once, while future additions will allow for multiple background threads. This marks the beginning of Modo taking greater advantage of modern many-threaded systems.
Incremental tool updates:
We’ve made significant accelerations to 10 of Modo’s modeling tools and MeshOps. This includes a system-wide change to VOs and further optimization of tools. The updates applied across the 10 modeling tools also have an impact on additional tools, due to Modo’s modular nature.
OctaneRender bundled with Modo:
Modo 17.0 brings a single GPU version of OctaneRender, in collaboration with OTOY. This gives artists access to the fastest and most reliable GPU renderer on the market. You’ll be guided through the registration and licensing process for OTOY from within Modo. What’s more, OTOY enables you to upload your scenes to its GPU render farm for a more streamlined experience. The Modo plugin is one of the most robust Octane plugins for DCCs and Foundry is committed to working with OTOY to keep it that way.
AVP Improvements:
Artists now have the ability to toggle textures on or off, without the need to go into the Shader Tree, thanks to improvements to Modo’s Advanced Viewport. The new default AVP setting means you can view environment lighting and any viewport lighting at the same time, so that you can make sure that all your lights interact as they should. We’ve also improved wireframe drawing, along with the visibility of MeshOp handles and selections.
Procedural modeling experience enhancements:
Thanks to a combination of VOs and incremental updates, MeshOps are now processed faster for a much more interactive and engaging experience. This is the first in a planned series of performance updates for 2024, which will see the performance of Modo continually improve. We’ve also improved many of the UX and workflow interactions with MeshOps.
Decal workflow improvements:
With Modo 17.0, it’s now faster and easier to use decals, and wrap flat images onto complex surfaces with minimum distortion and no UV creation needed. Combined with VOs, decals are now more predictable and valuable than ever before.
PolyHaul enhancements:
PolyHaul was introduced in Modo 16.1 to combine multiple modeling operations into a single streamlined tool. We've made the UI easier to navigate, and also added the option to use it in conjunction with Falloffs, for maximum precision. What’s more, we’ve also refined how PolyHaul deals with switching between modeling modes, ensuring that quality geometry is created.
Primitive Slice enhancements:
Modo 17.0 makes it possible to use clones with the Primitive Slice. This means artists can create multiple slices of the same shape at once, reducing the need for repetition when adding multiple slices to a mesh. We’ve also added Corner Radius for working with rectangles and squares, so that you can round corners of the shape that’s being sliced. This means you can make quick adjustments to slices, without the need to switch between multiple shapes or presets.
Mesh Cleanup enhancements - Fix Gaps:
Mesh Cleanup fixes broken geometry, and now includes Fix Gaps. This means that you no longer have to perform these operations manually, so you can stay productive and avoid interrupting your creative flow.
Radial Align enhancements:
Radial Align turns a selection into a flat circle. However, artists frequently need to have a partial radius rather than a complete circle. Modo 17.0 brings the ability to create a partial radial alignment, giving you more tailored tools to enhance your artistry.

New in MODO 16.0v1 (Apr 28, 2022)

Primitive Slice/Slice Effector Enhancements:
Primitive Slice and the Slice Effector tools enable rapid creation and iteration of boolean modeling from curves and profiles which is an essential part of modern modeling workflows. In Modo 16.0, we’ve added an array of enhancements to extend the capabilities and interactivity of these tools to expand the freedom of design exploration that Modo’s modeling toolset is already renowned for.
Conditional Loop / Seam Marker:
Selection in general has always been central to Modo’s potent modeling workflows. The Conditional Loop Tool builds on these powerful capabilities by allowing artists to define and control how loops are selected. Quickly add conditions that define whether you want to allow loops to cross each other or specify an angle where you want loop selection to end. Along with many additional capabilities, this tool provides valuable refinements.
Bridge Tool MeshOp:
Modo’s procedural modeling toolset continues to grow in power with every release. The addition of the Bridge Tool MeshOp introduces an assortment of impressive modeling capabilities that are certain to give artists and designers greater flexibility when leveraging Modo’s exciting procedural modeling system.
MeshFusion Variable Strip Widths:
MeshFusion makes it astonishingly easy to produce detailed, hard surface meshes. However, it is very easy to put MeshFusion in a state where the mesh can’t be drawn. Automated Variable Strip Widths adjust the start or end values of a strip automatically, to ensure that a mesh can be generated and visually notifies users where automatic adjustments have been made.
Wrap Effector:
Lattice and Wrap deformers are an essential rigging and modeling capability. Modo’s new Wrap Effector intelligently satisfies the needs of both types of deformation in one easy to use tool. Artists can easily tune how precisely a cage mesh deforms a target mesh, ensuring a desired result. The cage mesh can also exist inside or outside of the target mesh. Along with many performance refinements, the new Wrap Effector is a valuable and flexible addition.
Shader Tree Enhancements:
Modo’s Shader Tree offers a powerful and familiar stack-based approach to shading that can be leveraged in many unique ways. It has now been enhanced to offer visualization of blend modes and opacity to quickly assess how a material is assembled. Groups now display a graphic to specifically describe how a group is masking it’s contents. The contents of a group can also now be automatically reorganized by effects.
Intel Denoiser Update:
Render denoising allows artists to spend less time waiting for renders to complete. Modo’s legacy renderer and the new path tracer mPath both produce images very quickly but the vast majority of render time is spent refining those last bits of noise. With Intel’s latest updates to their denoiser, fine details are preserved more intelligently.
Auto Set Layer Effects:
Materials are often a collection of many images and each image affects a specific material attribute. For instance, an image that defines the color of a surface or an image that defines how transparent a surface is. These images often include the effect as part of the name of the texture. Auto Set Layer Effects will look at the name of an image when it’s imported to automatically determine the effect it should be set to and it let’s users define naming conventions.
Conditional Command:
As an artist develops a workflow, many actions are repeated. Conditional commands lets users define a condition that then automatically fires a command. For instance, maybe an artist notices that every time they go into vertex mode, they only ever use the vertex bevel tool. They could then use conditional commands to tell modo “Every time I click on vertex mode, activate the vertex bevel tool for me.” This further streamlines the user customization that has always been central to Modo’s owner.
Action Exporter:
Modo has a novel method of containing multiple animations for assets via the actor/action system. With Modo 16.0, actions can now be easily exported in bulk.
Ruler/Grid MeshOp:
Reliable measurement tools are an important part of asset creation and also for creation of visualizations. The Ruler/Grid MeshOp makes this easy for artists to set up as part of Modo’s procedural modeling system.
Rhino 7 Support:
Modo has supported native import and export of Rhino 5 .3DM files for many years. Rhino 7 contains many new capabilities that we are now supporting direct mapping for, including subdivision surfaces with creasing, curves, points/point clouds, and meshes in general.
Edge Subdivide MeshOp:
Edge Subdivide, which inserts a vertex onto an edge, has been added to Modo’s procedural modeling system. This also integrates seamlessly with Modo’s schematic workflows, allowing for precise placement of an arbitrary number of vertices along an edge.
Solo Snapping Mode:
Modo’s snapping system is diverse and robust. Users can leverage snapping simultaneously to many different types of components and items. However, many times you just want to snap to 1 type of item and that requires turning off many items. Now users can use alt-click to select a single type of component to snap to and any other types will automatically be disabled.
Non-Photorealistic Rendering 2 Kit:
Starting with Modo 16.0, the NPR 2 kit is now included for free for users with an active license of 16+.The NPR 2 kit lets you easily create unique hand-drawn looks when rendering in Modo. The stylized or expressive 3D capabilities of Non-photorealistic rendering (NPR) are useful in a wide range of applications—from technical illustration where edges and important features are emphasized to cartoons where simple colors and strong lines convey emotion.

New in MODO 15.1v2 (Apr 28, 2022)

Assembly Preset Workflow:
Modo’s Preset system and Assemblies have long been a valuable workflow component. The new Assembly Preset Workflow refines this further by simplifying the creation process and making presets easier to share. Presets are now packaged, containing associated content like images within a Preset Package. When you pass a preset to another artist, you can now be sure they have the supporting content that they need.
Schematic Enhancements:
The new Preset system automatically creates an assembly in your scene, more closely linking the relationship between presets and assemblies. Assemblies no longer need to have every element exposed in a schematic assembly. The Stack Nodes and Schematic now contain the elements needed to do more of your work without leaving Schematic.
Primitive Slice:
Curves are an essential component of modeling today. Primitive slice further elevates Modo’s curve modeling capabilities by allowing users to slice primitive shapes into geometry and even produce boolean effects with depth control when leveraging the procedural variant of the tool with the slice effector.
Edge Subdivide Command:
Simple features can have a big impact on workflow. Edge Subdivide simply divides each selected edge into multiple edges, making it easier to add vertices along an edge. This is tremendously useful for quickly modifying and refining topology.
MeshFusion Workflow Refinement:
In 15.0, Mesh Fusion workflow was completely reenvisioned. With 15.2 we’ve taken this further by removing Fusion Selection Modes. Now you simply select the element you want to modify and we give you the info you need.
Geodesic Distance Modifier:
Procedurally generating 2D designs on 3D surfaces is extremely valuable for designers. The geodesic distance modifier can be leveraged to find the distance between two points and trace a path between them on the surface. This enables generation of complex patterns that can drive exciting, procedural modeling results.
Set Vertex Normals + Largest Normals:
Control over vertex normals and vertex maps in general is a very important part of 3D in general and specifically for real-time renderers. The largest normals option is now a part of material smoothing properties. The color tool and Set RGB node now have an option for Discontinuous values, eliminating color blending across the boundary of a selection. Finally, a Set Vertex Normals MeshOp has been added, further expanding what’s possible in our procedural toolset.
SelectionOp Stack Node:
Modo’s Order Of Operations system is extremely powerful. However, it can be difficult to understand the order of MeshOps and SelectionOps in the schematic viewport. The MeshOp Stack node was added in 15.1. In 15.2 we have added this ability for Selection Ops, better informing artists of how a stack relates to a node graph.
mPath Render Booleans:
mPath is Foundry’s powerful new hybrid pathtrace renderer. In 15.2 we’ve added Render booleans. This makes it incredibly easy to create cross section cutaways for product and graphical visualizations.
TuneUps:
With every release, we try to touch on existing features and workflows with meaningful refinements. The Script Editor has received many improvements to make scripting a more comfortable experience. Convert Instances to Replicas makes it easier to switch between instancing and replicators. Playblast waits for Advanced progressive let’s artists take advantage of progressive antialiasing when creating viewport playblasts. And the PBR loader will now automatically add imported PBR textures into groups that already have the correct polygon tags.

New in MODO 15.1v1 (Jul 22, 2021)

Direct Modeling:
Modo defined what good modeling workflow means... With every release it has grown in power and flexibility. Users can rapidly create and manipulate geometry with a tremendous array of context-aware tools. New additions to the 15 series include Curve Booleans, many enhancements to geometry booleans and unsubdivide. Chamfer Edit has also been improved to support an array of new capabilities.
Procedural Modeling:
When we add or enhance a direct modeling tool, those changes are often also applied to our procedural toolset. This has led to a robust set of modeling tools that can be edited at any modeling stage. The 15 series has added support for Deferred and Paused Evaluation, Loop Slice, and MeshFusion Edge Weights to Strips. The Merge Mesh MeshOp has also been updated to allow for merging a specific procedural layer instead of the whole stack.
Rendering & Shading:
Modo is renowned for its powerful preview rendering window. mPath QuickCam is the first step towards adding this functionality to the new physically-based path trace renderer. Users can now navigate through a scene within the standard render window, including the ability to “look around” similar to game navigation. Dispersion is also now supported in mPath with minimal effect on render times, even with depth of field enabled.
Animation & Rigging:
Rigging and Animation are often treated as an isolated set of features in other applications. Instead, Modo treats these tools more holistically, emphasizing their use in asset creation, design iteration and communication. The Stack Node enables visualization of stack-based relationships within the schematic node graph. Rig Clay, enables user-defined gestural control and now supports control of meshops.
Performance and Continuity:
With every release of Modo, performance improvements are treated as a feature. We’ve added support for Python 3 and QT5. The MeshFusion Workflow overhaul addresses performance from a workflow and design perspective making MeshFusion a more joyful experience. Deferred and Paused Evaluation improves interactivity for MeshOps and Deformers, reducing performance bottlenecks.
Viewport:
The viewport in many 3D applications started as a quick preview renderer. Modo helped evolve the role of a viewport into a functional and customizable authoring environment. Enhancements to command regions and rig clay further this commitment. The addition of depth-of-field to the advanced viewport lets users refine camera settings interactively without having to launch a full render and the new MeshFusion workflow emphasizes viewport-centric workflows, setting the stage for the Modo vision of what the future of content creation will look like.
Workflow and User Experience:
Modos features have always been engineered with workflow and user experience as the highest priority. OmniHaul provides customizable, gesture-based control for tools and channels directly in the 3D viewport. Enhanced boolean functionality, expanded preset capabilities and the new MeshFusion workflow introduces a completely new interaction paradigm that is the foundation for defining the future of modeling workflow.

New in MODO 15.0v1 (Apr 7, 2021)

MeshFusion:
MeshFusion has received a major revamp in Modo 15.0, with the UI being simplified and an emphasis being placed on a viewport-centric workflow for editing models. The inclusion of new selection modes such as Auto-Select, Source Select and Edit Attributes also now allows users to directly interact with their models, making it easier than ever to just click on a patch or source mesh to edit Surface Strips and Skirts. MeshFusion's UI has also had a major overhaul, with windows and menus being simplified and compacted, making navigation easy and quicker than ever before.
Select Source Mode:
Select source is a new mode in Modo 15.0, that allows you to select your source meshes in the viewport, instead of from the items list. Multiple source meshes can be selected and edited at the same time, making it easier and quicker to use MeshFusion than before.
Edit Attribute Mode:
Edit Attribute is another new mode in Modo 15.0 that helps to make usability a breeze. Edit Attribute allows you to isolate and edit single strips, patches and corners, making detailed edits and detailing a much simpler task.
Edge Weighting and Zero SubDivision:
MeshFusion also now supports truly accurate Edge Weighting. When used in conjunction with MeshFusion's zero subdivision functionality, this allows for traditional cage-mesh boolean operations without subdivision surfaces while also allowing you to take full advantage of MeshFusion's powerful tools such as Fusion Strips and Patches.
Direct Modeling:
Chamfer Edit Enhancements:
The Chamfer Edit tool has been updated to allow the editing of rounded bevels. By ensuring that source segments are set to the same segment amount used, you are now able to change the offset, segment amount and curvature of a beveled edge with ease, making editing complex models a smoother and speedier process.
Cage Mode:
Modo 15.0 now allows you to enable cage mode by setting the subdivision level of a mesh to zero. This UX change cuts down on the amount of mouse clicks needed before a tool is ready to use and in turns allows your workflow to become more streamlined and efficient.
UnSubdivide:
UnSubdivide is a brand new modeling tool in Modo 15.0 that allows you to reconstruct subdivisions in reverse and output a low density mesh. Perfect for creating low poly meshes for baking and optimization, this tool is available as a traditional tool in the modeling tool box, or as a procedural tool in the Mesh operation window.
Procedural Modeling:
Create Vertex MeshOp:
This simple operator creates a single vertex and can be positioned in your scene by inputting coordinates in the X, Y and Z parameters.
Offset Curve by Mesh:
Bezier, B-Spline and Polyline curves are now supported by the Offset Curve by Mesh operator.
Procedural Loop Slice:
Loop Slice has now been added as a procedural tool, allowing you to create evenly spaced edge loops by a specific count number. Additional parameters such as Preserve Curvature and Split have also been included in the procedural version of this tool, to allow for in depth and advanced editing while using a procedural workflow.
Animation & Rigging:
Animation Editor:
The animation workspace this release has also had a major overhaul. The lower collapsible Graph Editor viewport layout has been replaced with a new layout that contains the Graph Editor and Dopesheet along with a Channels viewport, allowing for quick and easy navigation that is both beginner and seasoned professional friendly.
Command Regions and Rig Clay Enhancements:
This powerful tool allows you to do away with the clutter of controllers on a rigged mesh, and is now supported in the 2D model view; adding more flexibility to the types and complexity of rigs that you can create.
This tool has also had its procedural workflow updated, with Mesh Operation nodes having been added for Polygon, Edge and Vertex Command Regions.
Rendering and Shading:
Interactive mPath Renders:
Modo's mPath renderer has an interactive mode, which allows you to pan, zoom, and rotate the camera in the Render viewport without adjusting the camera in the scene. See Rendering with mPath.
Viewport:
AVP Depth of Field:
This new addition to the advanced viewport now allows users to refine camera settings within the 3D viewport properties window, without the need to fire off a render. This powerful new tool is supremely useful for setting up renders or laying out scenes in a higher detail without the hassle of waiting for a test render.
Workflow and User Experience:
Licensing Modo:
How Foundry products are activated has also had an update, with the introduction of Cloud based licensing in addition to our traditional RLM licensing, making it easier than ever before to activate and manage your products. The activation window has also had a total revamp, making it easier to log into your Foundry account, select products to activate and see the expiry dates of your licenses.
FBX Loader:
Modo's FBX importer has been updated to show import progress through sub-monitors. This gives you the ability to view what part of the FBX file is being imported, allowing for a more granular view of the loader.
Quick Command Buttons:
The Quick Commands buttons have now been split up, and now sit above their relevant panels instead of being grouped together. This makes the UI easier to navigate, making their respective functions quicker and easier to use.
Python 3 Support:
Modo 15.0 also now supports Python 3 as well as Python 2. This can be easily changed in the system dropdown menu, and it's easy to now switch between the two.
SDK Docs update:
The Developer wiki has also been updated and is now available here (https://learn.foundry.com/modo/developers/latest/SDK/index.html).

New in MODO 13.0v1 (Mar 27, 2019)

Offline GPU Rendering with AMD’s Radeon™ Pro Render:
AMD’s GPU accelerated path-tracer, the Radeon Pro Render, is now part of Modo’s collection of powerful rendering options and the beginning of increased rendering flexibility and improved APIs in Modo. In its first iteration for Modo 13.0, this hardware-agnostic, offline rendering solution gives artists the option of leveraging hardware that was once limited to real-time viewports.
AMD’s powerful denoising technology has also been added in 13.0. This provides users with additional options to reduce render times by accessing one of two options available: Bilateral and Median. Much like Radeon Pro Render, AMD’s denoiser is not vendor-specific and further expands the rendering options available to all users on Windows and OSX.
MeshFusion adds Kit Fusing:
Modo’s direct modeling toolset remains the most intuitive experience for 3D artists with new features including Relax Edge and Find Shortest Path Selection to enhance and accelerate creation workflows.
Building on our award-winning MeshFusion toolset, Modo 13.0 introduces Kit Fusing, allowing artists the ability to define only a portion of a mesh to be used for creating boolean operations. This powerful enhancement makes it easier to leverage complex meshes and allows for holes to create the impression of complex negative forms like fan grills with mechanical components that are visible inside a surface.
Elevated Animation Workflows with Layering Systems:
The world’s leading riggers and character artists use Modo for games, film, and TV. Using their feedback and driving Modo in production environments, we’ve been able to engineer solutions that target animation workflows. Modo’s 12 Series included huge advancements to the schematic viewport, providing a cleaner and easier-to-manage artistic experience with features such as Notes to enhance collaborative pipelines. Modo 13 adds non-destructive editing of specific actions through the new Animation Layers feature, where each layer can be controlled to override or apply additively in a top-down format.
Masking with the new Animation Layer system allows for individual aspects of an animation to be isolated and uniquely defined.
Arrays Elevate Modo’s Procedural Modeling Capabilities:
Modo is unique in how it enables users to create customized workflows tailored to the needs of an artist or project. Arrays are a new addition to Modo’s rigging system that allows for advanced storage, manipulation, and output of data in a variety of forms, further enabling what technical artists can engineer in Modo. Arrays help you construct complex relationships that can be leveraged across Modo’s many systems including, rigging, procedural modeling, particles, and more to create the specific tools and behaviors you need to realize your creative vision, whether it’s a custom modeling tool or an advanced motion graphics system.
Modo Bridge adds Unity Support:
Modo Bridge for Unity adds similar functionality that was present in the Unreal Bridge, now through a shared interface to streamline interaction with real-time scene creation. Users can transfer Meshes, Instances, Textures, Materials, and Cameras between Modo and Unity with bilateral communication, allowing artists to move items back and forth between either application.
UV Enhancements:
The UV toolset in Modo 13.0 has been further simplified to dramatically reduce the time required to generate clean UV maps. The new UV Cut Map allows artists to define sets of selections that are color-coded and displayed on the model in the 3D viewport. Enhancements to the UV Split, Wireframe Display, Packing, and the Edge and Vertex Slide bolster the Modo UV arsenal, allowing more control of the unwrapping and utilization of complex UV maps.

Improvements have been made to the CPU performance when working with vertex normals. Vertex normals
Provide an efficient way to smooth shade a polygon mesh, giving it the appearance of a much higher poly mesh.
In addition, the rendering process is approximately 50% faster.
UI:
Bounding Box Threshold:
A Bounding Box Threshold option has been added to the OpenGL Display Preferences. It allows you to draw
Items as bounding boxes above a specified GL polygon count, when the scene is rotated, panned, or zoomed in
The viewport. This makes working with large scenes easier by eliminating delay in the viewport.
Release Notes for Modo 12.2v1 |
Clip Choice and Preset Browser Improvements:
Improvements have been made to the Clip choice and the Preset Browser to make them faster, more visually
Consistent, and easier to navigate. Thumbnails are now saved as part of the Dir cache when using Clip Choice.

Changing the color of the locked elements, is done in the Systems > Preferences > Display > Color >
PSUB Mask settings.

New in MODO 12.1v1 Build 504533 (Jun 21, 2018)

Integrated VR Viewport:
The new integrated VR viewport allows you to connect to a VR headset and view and adjust your model within a virtual environment. This release focuses on Item transformation, scene layout, and design review. A number of key Item editing tools are available, including move, rotate, scale, instance, duplicate and transform reset. There are also snapping options and action centres available, allowing you to accurately move objects around in your virtual environment.
Rendering and Rigging:
The Advanced Viewport has seen significant improvements, allowing you to render more complicated material setups directly in the viewport and make changes in real time. With Group Masks fully supported, you can mask multiple material layers and render highly complex, multi-layered material setups. There’s also full support for group blending modes and opacity changes, resulting in little difference between the representation of a material in AVP and in Modo’s native renderer. Other rendering improvements include the addition of a Film Roll channel, which allows you to animate a two dimensional roll of the camera relative to the camera’s film offset channels: useful in 2D animation pipelines.
UV tools and MeshFusion:
A major update to the UV Pack command brings a new algorithm that provides faster Packing times. The distance between UV islands and UV border can now be more accurately controlled with the Gaps by Pixel Option. There is a new option to Pack to a new UV map, preserving the original. And a further major addition is the ability to Pack based on Polygon Tag, which gives the ability to pack UVs to separate UDIMs based on that tag. Additional settings have been added to MeshFusion Surface Strips, giving you greater control over the generated topology.
Animation:
Modo 12.1 introduces animation workflow enhancements designed to speed up the keyframing process and reuse keyframe data. Driven Actions add the ability to reuse, retime and rig action clips in a scene, allowing you to fully utilise Actions for the first time. There’s a new default key slope type, providing smoother interpolation between keys, vastly reducing the amount of key adjustment required whilst animating. It’s now much easier to manipulate multiple keys in the Gradient Editor using the new Box Transform Tool. The Mini Gradient Editor brings a number of improvements including the addition of a menu that allows you to save and load presets.
Procedural Modelling:
Modo’s procedural modelling system continues to improve, with a range of new Mesh and Selection Operations. The ‘Surface Constraint’ mesh operation is a procedural version of the Background Constraint, which allows you to procedurally constrain geometry to another piece of geometry in the scene. Other key additions include the Convert Selection, Select Connected, and Select Loop selection operators, and the Edge Slide, Push, Edge Split, Polygon Merge and Polygon Unify mesh operations. Watch our videos for a full run-through of all these new features!
Direct Modelling:
Modo 12.1 brings significant improvements in editing and defining vertex normals. The Vertex Normal Toolkit has been updated to make it simpler but with more options for hardening or softening by specific component, by endpoint, by angle, by polygon boundary, UV boundary, and UV island boundary. There’s a new Smoothing Group manager: a UI for defining and visualizing the groups within which polygons exist. The vertex normals of a model are stored as part of Modo’s native smoothing rather than a separate vertex map, so models can now be freely edited and deformed without adverse effects on smoothing. A variety of new options for controlling surface normals have been included as part of Material Properties. And there are options for controlling the effect of smoothing groups on a per material basis.
UI Improvements:
Modo’s UI has been tweaked: To allow faster access, the tool palette buttons can now swap the tool palettes directly in the form. It’s now possible to toggle things like background mesh visibility, item drawing, weight map visibility and distortion directly in the 3D viewport, making these options easier to find and giving a clear visual indicator of their state. The Modo modes form includes a set-up mode button, render button, and nested center and pivot mode buttons, allowing for further consistency between layouts. And all KITS now exist in a KITS popover form, accessed via the KITS button in the top right of the UI. Modo also comes with a new Beta layout, showcasing a number of new UI concepts for working in a single layout.

New in MODO 12.0v1 Build 492947 (Mar 28, 2018)

glTF 2.0 Export to Facebook:
Developed in conjunction with Facebook's new ‘3D Posts’ functionality, artists can now create 3D objects in Modo and then share them on the Facebook News Feed. Facebook users can then grab, spin and interact with the objects to look at them from all angles. This technology presents artists with a unique opportunity to create more engaging and compelling content, whilst offering users the opportunity to enjoy interactive 3D experiences on Facebook.
Mesh Paint Refinements:
Modo's Mesh Paint tool has been brought up-to-date and enhanced, allowing you to quickly bash out models and environments faster than ever before. With the ability to now paint random presets, you can utilize asset libraries in new and exciting ways, and the new array paint modes give you greater control when painting more ordered collections of objects.
MeshFusion Surface Strips:
MeshFusion is significantly enhanced with Surface Strips, an innovative new feature that works by allowing the creation of strip geometry or topology that lies flush on any Fusion Item surface. This provides a wide range of opportunities for Post-Fusion modeling with either Procedural operations or direct modeling of the Fusion Output Mesh. The most obvious examples are channels and ridges along arbitrary paths — but the range of applications is much much wider, allowing artists to explore iterations more creatively than ever before.
Modeling and Design Creation Enhancements:
The Jitter tool has new options to randomize the position, scale and rotation of connected geometry within a single Item. It also works with connected selections, allowing you to quickly add subtle realism in situations where previously it would have been difficult. It’s now possible to model even faster in a single 3D viewport by moving objects towards you and away from you without having to interact directly with any transform handles. And a new tool handle has been added to the Vertex Slide tool, giving you greater control when tweaking the position of vertices in a mesh.
New Procedural Mesh Operations:
A Triangulate MeshOp has been added, which lets you export triangulated models in a non- destructive manner. The Merge Mesh operator can now read replicator items as geometry inputs, allowing replicated geometry to be manipulated using procedural modeling tools, and providing an easy way to convert a replicator item into a single mesh item for export. It’s now possible to modulate the shape of an Item Falloff via the Mini Graph Editor, allowing for a much wider array of falloff effects when rigging or procedural modelling. The new Falloff Operator lets you drive Mesh Operation Falloffs via a range of scene and geometric parameters.
Cloud Assets and Foundry Share Site:
Creating, sharing and downloading preset assets has been improved. Cloud Assets can now be dragged and dropped into the item tree or directly into the Modo viewport. Just want to download the assets and not apply them to your scene? Use the new download badge that appears in the upper left of the preset thumbnail. The process of preset creation has also been significantly streamlined. It’s now possible to create any preset type by simply dragging from it's location in the UI into any preset browser.
UV Tools and Workflow Refinements:
Modo's fast and nimble workflows continue to be refined, with UI optimization and new toolbar menu options making it easier to manage 3rd party Modo Add-ons. The Modo Modes toolbar has been re-organized for more consistency, with a number of modes now having improved workflows, vastly reducing the number of clicks involved in a standard Modo modelling session, while the UV viewport has new buttons to give easy access to a range of common display options. The Fit UVs command has new Gaps options to set border padding. Also, it’s now easier to align multiple UV selections in one go.
The Hatchet Collection:
Modo 12.0 comes with a selection of python scripts from the popular Hatchet Collection, enhancing core functionality in Modo and making asset creation even more efficient. There's a wide variety of tools to convert curve types, offset curves, select random, and much more.
Advanced Viewport GPU Acceleration:
The Advanced Viewport in Modo now uses Multi Sample Anti-Aliasing (MSAA) GPU hardware to speed up anti-aliased rendering. This is a faster, rough and ready version of an also-available Supersampling method. The new GPU powered Anisotropic texture filtering provides superior viewport texture quality in virtually all cases, at the slight expense of performance.
Rendering and Shading Improvements:
Providing a much more flexible way of rendering specific frames, a new frame range channel has been added that controls which frames are to be rendered during animation rendering. The new glTF Material Shader allows for complete WYSIWYG between Modo's native renderer, the advanced viewport, and any other application that supports the glTF shading model. A Shading Model drop-down has also been added that includes both PBR & Unlit settings.

New in MODO 10.2v1 Build 126693 (Oct 14, 2016)

New Features:
Animation:
Deformer Caching:
The output of mesh operations and deformers can now be cached when animating a scene. When frames are cached, performance is limited mostly by GPU drawing performance. The Cache Deformers options greatly improve playback speed, at the expense of using more memory.

For moreinformation aboutsketching guidecurves, seeRetopo Guides.
Theautomatic retopologyimplementation converts amesh into amesh madeup of all 3-, 4-, and 5pointpolygons of auniform size. To determinethis polygon size, itlooks atthenumber of polygons you requestin theoutput, and divides thesurfaceof theareabythatnumber. As aresult, thetarget polygon number, either as anumber or apercent, is onlyapproximate. An option to applya subdivision to themesh to producepurequads is also available.
Theretopologyalgorithm can detectsharp edges in theinputmesh and preservethem bylooking for faces thatmeetatan anglegreater than thecreaseangleyou specify. Although theprocess is automatic, you can guidetheresults using standard Modo mesh attributes, liketheRetopoDensity weightmap, or theRetopoEdgeLock and RetopoFlowedgeselection sets.
Detriangulate
TheDetriangulatetool removes diagonal edges. Itallows you to control flatness thresholds and to specifyoneor mores edges to actas guides for wherethequads are.
RetopoGuides
This tool allows you to sketch curves (polylines)on asurfacethataresetup as either position or edge flowguides for automatic retopology. Thecurves aretagged with thespecial selection setnamethat theautoretopo command looks for, and theyhaveavertex normal map with normals taken from the surface. Theseareboth necessaryelements for autoretopo.
You can activatethetool byclicking on theRetopoGuidesbutton in theTopologylayoutunder the Toolssub-tab.
AutomaticComponentSelection
In AutoSelectmode, Modo automaticallyswitches between Vertex, Edge, and Polygon selection mode, depending on whattypeof componentyou click on.
Enable/DisableCameraImages
You can nowenableand disableforeground and background images in theCameraitem's properties.
FadingGrid
Thegrid nowfades outaround thecorners, providing asenseof depth and distance. Red and blue color highlights for theXand Ycenter axis can also beenabled to help keep your orientation.
ItemModeWireframeandSelectionDrawing
Selected items nowalways drawtheir wireframe, even if wireframedisplayis disabled. Optionally, the item selection can bedrawn with asolid fill instead.
ItemWorkPlanes
To makealigning theWork Planeto items easier, you can nowright-click on an item in the3D viewportand align theWork Planeto thatitem.
MorphedMeshDrawing
Morph maps can bedrawn as acage, with various drawing styles, with vectors drawn as line segments from thebasemesh to themorph mesh, and with color and opacitysettings for themorph cage.
PrimitiveToolHandle
Additional controls havebeen added for theinteractivetools. Thetool handles can noweither adjust around alocked central location, or lock theoppositesideto thegrabbed handle, making them easier to use.
ProficiencySwitchinginForms
Panels thatcontain controls with differentproficiencylevels nowshowLessand More buttons atthe bottom of theview, allowing you to displayfewer or morecontrols.
VertexDrawingOptions
Vertices arenowautomaticallyvisiblein Vertex mode, butnototherwise. Theycan still beexplicitly enabled in other componentmodes.
WorkPlaneAligntoScreen
An option to align thework Planeto thePerspective viewhas been added to makecertain modeling tasks easier, such as drawing curves using Sketch.
WorkPlaneBookmarks
Work Planebookmarks can nowbeassigned to polygons and re-used later on. This is useful to store construction planes in thegeometryitself. Work PlaneBookmarks work in awaythatis verysimilar to selection sets. Differentbookmarks can besaved for each of your scenes.
WorkPlaneVisibilityOptions
Newviewportvisibilityoptions havebeen added to providemorecontrol over themain grid and the Work Plane.
Miscellaneous
CopyTransforms
Theitem.copyTransformscommand has been added, which copies transforms from oneitem to another. Unliketheitem.align command, this newcommand copies all animation and rigging as well.
MaximumEnvironmentResolution
Anewpreferencefor environmentresolution has been added to theDisplayPreferences. Reducing theresolution increases performancewhen editing theenvironment.
NumericControlColorCorrection
Numeric control color correction applies color correction to thenumeric values displayed in color fields. For example, this allows you to copyand pastethehex codefor acolor from Photoshop into Modo and havethecolors match. Previously, Modo supported color correction for thedrawn representation of acolor in theUI butthenumeric values werealways drawn in linear space.
ParticleIDChannel
Locator items nowhaveaParticle ID channel thatcan beused to drivetheParticleID assigned to rendered surfaces. You can setthis valuemanuallyor driveitbyarig and then feed itto Shaders. This is mostlyuseful for Gradients and TextureSwitch.
SimulationModifiers
Simulation Modifiers provideways to control animated behaviors based on settriggers.
StringEncodeModifier
This is asimplechannel modifier for turning anumerical valueinto atextstring with optional decimal precision and leading zeroes.

New in MODO 10.1v1 Build 117244 (Jul 7, 2016)

Modo 10.1introduces a powerful, flexible, and robust new procedural modeling system that works side-by-side with Modo's best-in-class direct modeling toolset. With Modo 10.1, artists can iterate more freely with the ability to manipulate modeling operations at any time in a flexible layer stack. Create infinite variations using procedural operations that can be driven by textures, falloffs, or dynamically changing inputs; and easily accommodate change requirements with the ability to edit selections and swap out input meshes after the fact. New curvetools, constraints, deformers, and enhancements to the MeshFusion toolset complete the Modo 10.1modeling updates.
Mesh Operations:
At the heart of the procedural toolset are mesh operations. These are single layers within the procedural stack that are evaluated to modify the input mesh in someway. The operation can be simple, such as setting a material tag, or can be complex, such as filling a closed curve with polygons. The mesh operations are layered on top of each other in the procedural stack, and the stack is evaluated from the bottom up, passing the modified mesh from one operation to the next.
In addition to the newmesh operations, a subset of existing tools also have procedural equivalents.
Assign Selection Set:
The procedural Assign Selection Set mesh operation stores a collection of mesh elements - vertices, edges, and polygons - in a selection set, so they can be re-used at a later stage in the procedural evaluation. This can be useful for operating on the same set of mesh elements across a series of operations, or to store a selection for later use.
Curve Fill:
The procedural Curve Fill mesh operation fills closed curves with quads. External curves are filled, and internal curves can be used to cut holes in the closed shape. The operation provides two filling methods: grid and paving. The grid method creates quads aligned to a world axis, whereas the paving method fills a closed curve from the outside in, attempting to maintain a nice border around the edge of the filled shape. Settings are provided, allowing control over the fill density, polygon type, and UVs.
Material Tag:
This mesh operation sets the material tag on all marked polygons on a procedural mesh. These tagged polygons can then be used in the Shader Tree to mask textures and shaders.
Merge Meshes:
This operation merges multiple mesh items into a single procedural layer. An option to maintain the world transform, it transforms the merged mesh by its world transform.
Transform UVMap:
This operation transforms a specified UV map on a procedural mesh item. You can manipulate the tiling, position, and rotation of the UV map.
Freeze:
This mesh operation rasterizes non-face type polygons into face polygons. This is useful for converting text polygons into regular polygons, which can then be used with other procedural tools.
Edges to Curves:
The Edges to Curves operation converts edges into a series of curves of various types. The operation can either create multiple disconnected curves for each edge, or it can create one continuous curve from a series of connected edges. When combined with the Select by Border selection operation, the Edges to Curves operation can be used to easily convert a polygon island into a curve outline to be used with the Curve Fill mesh operation.
Lace Geometry:
This operation extrudes a profile shape a long a guide curve. The profile shape can either be provided by a custom mesh, a content preset, or a pre-defined shape, such as a circle, square, or rectangle. As the name suggests, this operation is useful for creating geometry, such as laces on a shoe.
Spline Primitives:
The Spline Primitivetools allow simple spline shapes to be created, both procedurally and non-procedurally. You can create a series of shapes, such as Circles, Stars, Squares, Rectangles, and so on.

New in MODO 902 (Dec 11, 2015)

New in MODO 901 (Dec 11, 2015)

Now included with every seat of Modo 901, MeshFusion takes away the challenge of complex and frustrating Boolean operations, making it easier to consistently produce high-quality models. You can interactively intersect, add and subtract subdivision surface (SDS) objects, control the blending between, and intuitively edit the assembly instructions. MeshFusion also comes with a library of preset primitives that you can use to construct your object; final output is a watertight mesh suitable for further editing in Modo or export to .stl.
Animation workflow enhancements - Various navigation enhancements and commands were added to the following animation tools:
Time tool
morphDeform.create command
Channels
Keyframes
Spacing Chart
Constraint Modifier - The constraint modifier is a new feature of Modo 901 that allows you to glue objects by proximity or contact, clump them by volume or area, and support multiple constraint types, with clear viewport representations of the glued groups. For more information on using the constraint modifier, see Constraint Modifier.
Procedural Shatter - Modo's new procedural shatter item lets you automatically shatter meshes based on collisions. For more information on how to apply procedural shatter, see Procedural Shatter.

Viewport UV Edge Seams and Boundary Edges - You can now choose to display UV edge seams and boundary edges with different colors in the 3D Viewport.
Switcher Bar - This new UI addition allows you to easily switch between layouts. It is similar to a root-level tabbed viewport, but provides extensibility and an easy way to hide tabs that you don't want to see.
Visibility Options for Performance - In Modo 901, viewport visibility of fur, displacement, mesh smoothing, and Shader Tree layers can be disabled for all meshes to enhance viewport playback speed.
Tiled EXR Conversion - In Modo 901, you can convert existing scene image clips to Tiled EXR, using various export options, saving the image alongside the original or in a new location. You can also access the converter through the command system. For more information on this, see Clips List
OpenEXR 2.x Support - The Modo 901 OpenEXR library has been updated to version 2.x. For more information on image formats, see Write Formats.
MDD Export - Modo 901 contains a set of commands, allowing you to export selected meshes as MDD point caches. For each selected mesh, a single MDD file is created, containing all of the vertex positions over the specified time range. This can be useful for exporting animation to another software package, or for round-tripping back to Modo as part of a production pipeline. For more information, see Export MDD.
SVG Mesh and Image items - Modo 901 supports SVG files: you can use SVG artwork as texture files or as curves that can then be manipulated in 3D, or act as a framework for you to construct meshes. Edited vector compositions can also be exported to SVG for use downstream in the design or manufacturing process. For more information on SVG files, see Import and Export File Formats in Modo and Write Formats.
Categorized Mesh Properties - Modo 901 minimizes clutter in the Properties panel by breaking surface data and curve data into separate sub-tabs. For more information, see Mesh Item.
Mesh Cleanup - The new Remove Disco Weight Values command allows you to remove unnecessary discontinuous weight values from Weight Maps in active meshes. For more information, see Mesh Cleanup.
Topological Symmetry - In Modo 901, you can work with models that are topologically but not spatially symmetrical, so you can edit both sides of a posed model at once. For more information on this feature, see Symmetry.
Freeze Deformations into Morphs - a new option in the Freeze command, Save Deformation to Morph, allows you to automatically save a mesh's current deformed state as a relative morph map. For details on how to do this, see Freezing Geometry.

Multi Edge Slice - This new feature allows you to cut multiple polygons at once. For more information, see Edge Slice.
Add Loop and Add Point Improvement - These tools have a new option, called Split at the Middle. For more information on this, see Add Loop and Add Point.
Fill Quads Pattern Fill - A new grid pattern mode that fills any open holes within a mesh with only quad polygons. For more information, see Edge Tools.
Calculate Mesh Volume - A new Calculate Mesh Volume command is available at the bottom of the Items list. For more information, see Item List.
Calculate Mesh Center of Mass/Gravity - This new command calculates the center of mass/center of gravity for a mesh and places a locator parented to the mesh at that location as a visual aid. For more information, see Item List.
Convert UVs to Mesh - Modo 901 allows you to convert the selected UVs to planar meshes. For more information, see Convert UVs to Mesh
UV Flip and Fit Improvements - In Modo 901, the Flip UV command flips UVs per UV island at the center of the UV island by default, and a Fit option was added to the Fit UVs command. For details, see Flip UV and Fit UV.
Masking with Gradients - Modo 901's Parametric Ink tool has a new Mask option that lets you use parameters including displacement, slope, altitude and incidence angle to vary the opacity of the applied paint. For more details on this feature, see Inks.
General painting improvements - Modo 901 delivers faster, higher quality painting, with better blending, interpolation, stroke evaluation, sub-pixel sampling and brush orientation during drawing among the improvements, leading to a superior overall experience.
OpenSubdiv - Modo 901 now supports the OpenSubdiv library. The OpenSubdiv options are available in the Mesh Item's properties. For more information, see Mesh Item.
Drop Mappers - This is a new viewport embedded in the Drop Mappings section of the Preferences that allow you to change the order of drop actions relative to each other within specific modifier combos.
Material Presets - Modo 901's presets allow you to easily click and drag out materials per item, without having to create an additional item mask.
Preset Browser - Before 901, Modo kept the directory cache up-to-date by scanning the disk for changes to the hierarchy when you switched back to Modo from another application. By default, Modo 901 updates the cache only when it is actively being used. You can change this back to the pre-901 behavior in Default Preferences > Application > Dir Cache Updates.
Image Path Utilites - Modo 901 has new commands that help manage image files used in presets and fix broken image paths. The new tools are accessible by right-clicking on any preset in the Preset Browser. For more information, see Preset Browser.
Nodally Driven Render Outputs - Render outputs can be driven nodally, on a per-sample basis, through input channels for the color (Output Color) and value (Output Value) of each render output. This allows any shader or procedural texture to completely specify the pixels of the render output. See Driving Render Outputs Nodally.
Preview Updates - For information on the updates, see Preview Viewport.
Fast shading updates
Faster pixel convergence
Progressive Render Reset Prevention - Preview no longer restarts when you click in the UI when rendering in full resolution mode.
Progressive Render Auto-Save - When in full resolution mode, Preview can now auto-save the preview image at regular intervals.
Preview Slave - Preview can be set to Slave mode, meaning that it reacts to any changes to the current scene by saving the current render, reloading the scene and restarting.
Material Updates - For information on the updates, see Material.
Physically Based Shading Model - Controls how light and surfacing attributes are evaluated for final rendering.
New Defaults - Some material channel default values have been changed: Shading Model, Specular Amount, Specular Fresnel, Match Specular, and Blurry Reflection.
Use Refractive Index - Sets the specular amount at normal incidence by plugging the material's refractive index into the dielectric Fresnel equations. This accounts for the refractive index of the incoming ray's material as well.
Clearcoat Amount - This setting allows you to easily add an additional un-blurred and un-tinted reflective layer to a surface, simplifying the simulation of multiple layers of paint, which can be especially useful for automotive surfaces.
Deferred Meshes - In complex or geometrically-dense scenes the Deferred Mesh option works to convert an existing non-deforming mesh to an externally saved .lxdf file. This action removes the geometry from the scene, while remaining as a renderable element. The main benefits to using deferred meshes are a reduced memory footprint, better scene interactivity, and faster scene save times. See Deferred Meshes.
Tension Texture - The Tension Texture is a special case gradient that changes a surface's colorization or value based on the amount of deformation applied to it. This is done by either calculating the difference of angle between each polygon's deformed and undeformed states, or its difference in area.
Wireframe Texture - The Wireframe Textureis a special type of procedural texture that can be applied to draw lines along the polygon edges of the target surface.
Physical Daylight - When Physically-based Daylight is selected as the Environment Type, a few additional options become available, allowing you to fine-tune the look of the lighting simulation. Global illumination needs to be enabled in order for the Physically-based Daylight function to work. See Environment Material.
Direct Light Improvements - For information on the updates, see Render Item: Settings.
Multiple Importance Sampling (MIS) - MIS has been implemented for diffuse and specular shading due to area light sources, greatly reducing visible noise in some cases.
Directional, Point, Spot, Photometric, and Cylinder lights can now be made visible to the camera, to reflection rays, and to refraction rays.
Adaptive Light Sample Allocation - Modo 901 has a new direct illumination method that adaptively allocates samples from a global count to each light based on its estimated contribution.
Image Processing - There are now two ways to control the brightness of the rendered image for a particular render output and two types of tone mapping available. See Render Outputs.
Digital Matte Painting - A number of features specifically targeted at improving the texture projection workflow have been added, see Projection Shader and Texture Locator.
Render Hide Polygons - Polygons can be hidden for rendering with two new commands in the View system menu: Render Hide Selected and Render Unhide. Documentation for this feature is currently not available. The online help is continuously updated, so please check back later.
Mikk tangent space baking - Modo lets you apply a Mikk Tangent Basis to vertex maps. This provides greater compatibility with the Unreal engine and other engines that support Mikk tangent space basis. For more information, see About Tangent Space.
Gradient Fill Image - The Gradient Fill Image layer is a hybrid texture, as it is procedurally-generated gradient but it is based on a dynamically created bitmap image.
Whole Frame Network Rendering - Improves network rendering performance for animation renders, especially those with IC enabled. For more information on this feature, see Rendering Preferences.
Command Regions - Command Regions allow you to execute commands or scripts and to select other items in the scene by clicking on areas of a mesh. Command regions are defined from a selection of polygons on a Mesh Item and can be assigned a color to help identify them in the 3D views.
Channel Modifiers - Channel Modifiers provide you with different ways to procedurally control elements by overriding or modifying channel values as they are fed into other nodes in a schematic graph.
Channel Probe -The channel probe is a Channel Modifier that can read channel values from another item. The Channel Probe is primarily used to simplify assemblies. For example, suppose you have an assembly that requires multiple channels from a camera in order to work. In order to use the assembly, you would normally have to link up each required channel from the camera you want to use. Using a Channel Probe in the assembly saves time, requiring just one item link for the camera to allow the assembly to read as many channels as it needs. See Probe Modifiers.
Curve Constraint Effector - Modo 901's Constraint Effector has various workflow improvements. For more information on this feature, see Curve Constraint Effector.
Texture Switch - The Texture Switch Node allows you to dynamically choose between multiple textures based on an Input Value. The input textures connections are ordered from bottom to top, so that when Interpolate is on, only adjacent neighbors are interpolated. The Input Value is also wrapped, meaning that the last texture is interpolated to the first, and negative values are interpolated in the reverse direction.
Raw Texture Outputs - Raw Texture Outputs has been added to texture nodes to allow you to use the texture alpha directly in nodal shading.
Particle Constraints - This new feature allows for particles to move towards targets through constraints. For more information on Particle Constraints, see Particle Constraints.
Quaternion Channel Modifiers - A Quaternion is a complex data type that represents a rotation in 3D space. The Quaternion makes it easy to perform rotation transform operations such as Slerps (Spherical Linear Interpolation) and other complex transforms. See Quaternion Modifiers.
Sculpting Layers - Modo 901's multiresolution sculpting supports layers, allowing you control sculpting in multiple passes. For information on working with sculpting layers, see Sculpting Layers.
Background to Multiresolution Mesh - A new sculpting command that lets you generate displacement vectors for multiresolution meshes. For more information, see Background to Multiresolution Mesh.
Macro Recorder Controls - New controls have been added to the Command History viewport to make the Macro Recorder easier to access. For more details on the Macro Recorder, see Macro Recorder.
Drag and Drop - Modo 901 uses ILxDrop servers throughout the interface, providing context-sensitive drop operations in all viewports where drag and drop is supported.
Pinned Popovers - In Modo 901, popover forms can be pinned to the interface. For more information on pinning popovers, see User Interface Conventions.
PyQT and Py Side UI Support - Modo 901 brings Qt support to Mac OS X and Windows, already available on Linux.
Channel Cut, Copy and Paste - Channel values can now be cut, copied and pasted onto other compatible channels in Modo. For more information on how to do this, see Channels Viewport.
Volume Items in Schematic - Volumes sub-menu has been added to the Add... button in Schematic views to allow you to add volume items directly to the workspace.
Improved Drag and Drop - Schematic viewports now support improved drag and drop functionality, with additional pop-up options. For more information on this feature, see Schematic Viewport.
Drag to Expose Channels and Relationships - In Modo 901, you can now expose one or more channels as assembly inputs by dragging those channels onto the + symbol on the Input and/or Output nodes of the assembly. For more information on this feature, see Schematic Viewport.
Scripting: Query Item Node - To better support scripting of schematic operations, Modo 901 has a new command to query the node ID for an item in Schematic.
Assemblies Improvements. For more information on the following enhancements, see Schematic Viewport.
Assign Channel Handles from Schematic - In Modo 901, you can add Channel Handles to a node in the Schematic viewport by right-clicking on it and clicking Assign Handles....
When creating a sub-assembly from selected nodes, Modo 901 centers the node within the location of the original nodes.
When exposing external links of newly created assemblies, Modo 901 also exposes the relationships.
Exposing Individual Relationships - Modo 901 lets you expose individual input relationships of an item by right-clicking on the relationship row. You can also rename the exposed relationship by right-clicking on it.
Rock Item - The Rock Item automatically generates geometry that can be made to look like a variety of stone elements, such as pebbles, rocks and boulders.
Replica Rigging - In Modo 901, you can drive parameters of prototypes attached to Replicators (for prototypes with compatible implementation, such as procedural items like the Sphere and Rock items), as well as rigid rigs. Feature packages have been added to the Replicator so that it is aware of all particle features, and quantized variants for time and random variations.
Tool Global Flags - You can override the Auto Activate and Select Through flags with the Global Flags option in the Preferences panel. For information on this feature, see Defaults Preferences.
VDB Voxel - The VDB Voxel item allows you to render externally created simulations stored in the open-source VDB Voxel format, as well as generate volume data from meshes or particles. The OpenVDB format is a super-efficient method of storing hierarchical data structures.

Shader Tree Folder- More easily organize layers in the Shader Tree.
Shading Library- Scenes can contain a Library of Materials, like Presets, that can be easily applied and modified.
Rendering:
Render Preview- Greatly enhanced Preview viewport allows saving and loading of progressive renders, respects the Render items Antialiasing settings, allows Drag&Drop functionality, and provides a modal progress bar when rendering animations.
Render Curves- New option to 'Render Curves as Polygons' allowing users to use Displacement Maps. Radius Gradient option allows users to easily control the radius of the resulting curve along its length.
Improved Physical Daylight Illumination Model- The old method has been completely replaced by a much more realistic model.
Environment Fog- Fog can now be applied as part of the Environment material with a new 'Layered' fog option.
Environment Importance Sampling- New option for Global Illumination produces cleaner results using far less rays.
Animateable Render Camera- Current Render camera can be animated and assigned to individual Passes.
Render Proxies- Users can convert individual layers to render-time Proxies, external files that only load when rendering.
Vignetting- Physically accurate vignetting is available as an option for the Final Color render output.
Bake Geometry Cache- Convert complex rendertime geometry, such a Displacement and Fur to actual Mesh Items.
Interface:
701 Interface- New streamlined workspaces refine modo's already fluid workflow for even greater accessibility and speed.
Enhancement to viewport icons to maximize/minimize windows within a group and open the viewports Options panel.
Layout Switcher- New shortcut for layout switching increases productivity and screen real-estate by eliminating tabs.
Embedded gradient editors allow the easy modification of values for many items, such as curve width along its length, emission strength of particle along a curves length, tapering of Fur fibers and many more.
Drag to Toggle- Users can now simply drag over multiples of layers in the Items List to automatically toggle them all.
Colored Coded Layers- Coloring of layers in Lists viewports can be applied using the contextual menus.
Point-At Popovers- New Popover type of viewport points at the button that spawned the window.
Item List Keyboard Navigation- The keyboard arrow pad can now be used to navigate the Items list selections.
Viewport Display Options- New viewport controls to independently customize the display of active and inactive layers.
Miscellaneous:
Python Support- New Python interpreter allows much faster and broader Python support.
