New Features
Animation and Rigging
Groups and Channels Viewport Filters and Search
You can now filter the Groups and the Channels viewport. The Channels viewport can also be filtered in the Graph Editor.
Int Range Nodes
A set of nodes have been added for manipulating integer range values. They are:
• Int Range Bounds
• Int Range Clamp
• Int Range Merge
• IntrangeTest
Saving Envelope Presets from the Graph Editor
Modo now allows you to save and load Envelope Presets directly from the Graph Editor.
Schematic Improvements
The following improvements have been made to the Schematic viewport:
• Show Instance Connections - You can now view links from instances to their original objects. They are drawn with a dotted connector.
• Show Connected Nodes - You can now isolate a nodal network based on the selection of a single node. With an item selected, all other nodes not connected to that node are hidden.
• Elbow Node - This node helps you organize the Schematic by reducing the number of visible and crossing links.
• Draw Linear Link Option - You can now choose to draw Schematic links as straight lines, which are easier to read in complex networks.
• Comment Node - You can now leave comments in the Schematic using the Comment node.
• Backdrop Node - Backdrops allow you to group nodes into a container that can be collapsed and moved around.
• Organized Duplication - When you duplicate nodes, their layout is now preserved in the new nodes and they are selected ready to be placed in the Schematic. You can either duplicate a node with or without its connections.
AVP and VR
Selections Visible Through Geometry
Modeling in the Advanced viewport is now much easier as you can now see selections through shaded geometry in either a foreground or background layer.
Points Anti-aliased and Independent Point Size
Points are now anti-aliased in the Advanced viewport and they also respect the viewport point size options for both foreground and background mesh layers.
Modo VR Component Selection and Editing
You can now select polygons, edges, and vertices in VR, and use a set of common modeling tools.
File I/O
Unreal Bridge
Improvements have been made to the Modo Bridge for the Unreal Engine. Transforms are taken care of automatically, lights and cameras are now supported, data transfer speed has been increased significantly.
MeshFusion
• Hybrid Strip Topology - Modo allows you to add skirt geometry to surface strips to allow greater control over topology around strip surfaces.
• Fusion Instance Synchronization - You can now control Fusion Item instances. All or selected instances can by updated, and the source can be updated from an instance.
• New Corner Geometry - The mesh algorithm has been improved so the topology generated at the corners of a Fusion Item is quad-based, resulting in a much smoother flow of polygons. This improves both positive and negative corners.
• Surface Strip Command Tweaks - You can now quickly swap fusion states. Hold the Alt key to swap between Surface Strips' boolean states.
Modeling and Asset Creation
Coplanar Falloff
The new Coplanar falloff type affects faces that are located on the same plane as the selection and uses the angle between normals.
Depth Limitation Option for Snapping
A new Depth Limitation option has been added to snapping. With this option you can limit the snapping range to a specified depth.
Edges to Curves Improvements
A new Delete Geometry option has been added to the Edges to Curves mesh operation, allowing you to delete all non-curve geometry from the mesh. For more information, see Edges to Curves.
Linear Align Tool Options
New Align to First Selected, Screen Axis, and Axis Vector X, Y, and Z options have been added to the Linear Align direct modeling tool, allowing you to align selected vertices, edges, polygons, or UV positions along a line. For more information, see Linear Align.
Procedural Convert UV to Mesh
A new Convert UV to Mesh operation has been added that allows you to convert a UV map to a mesh item procedurally.
Procedural Curve Convert Tool
A new procedural Curve Convert mesh operation has been added to convert selected curves to either a regular, Bezier, or B-Spline curve type.
Procedural Curve Offset by Mesh
The Curve Offset by Mesh operation has been added, allowing you to create parallel curves for a curve, offset by a separate mesh item. This mesh operation is also used for creating double stitching.
Procedural Hard Edges
New mesh operations have been added to work with hard edges procedurally. They are Hard Edge, Hard Edge Convert, and Select by Hard Edges.
Procedural Jitter Tool
A new procedural Jitter mesh operation has been added to reposition selected items or components based on a seed number and a range value for the X, Y, and Z axes. It applies a random offset to each vertex for a more random, organic appearance.
Procedural Merge Meshes Polygon Types
New polygon type properties have been added to the Merge Meshes tool to specify what type of polygons you wish to extract from a mesh.
Procedural Pack UVs Tool
A new procedural Pack UVs mesh operation has been added to automate the process of organizing UV island data to fit into the desired UV space.
Procedural Rectangle Tool
A new procedural Rectangle mesh operation has been added to straighten quadrangle selections of UVs into rectangular sections. This tool has options to automatically position and to regularize the spans into even grids.
Procedural Select Ring Tool
A new procedural Select Ring mesh operation has been added to select all the vertices or edges at the same selection direction around the globe of the geometry.
Procedural UV Fit Tool
A new procedural UV Fit mesh operation has been added to scale the currently-selected UV data to fill the normalized 0 to 1 UV space. This is a very useful tool for optimizing UVs.
Procedural UV Unwrap
A new UV Unwrap mesh operation has been added, allowing you to create UV maps for meshes procedurally.
Procedural Vertex Set Position
A new procedural Vertex Set Position mesh operation has been added, allowing you to reposition existing vertices to a specific position by specifying new coordinates.
Procedural Vertex Split
A new Vertex Split operation has been added, allowing you to split a vertex into multiple vertices procedurally.
Stitching Workflow
Modo now offers a quick and easy workflow to add and build stitches using the Stitch Mesh Setup command.
Performance Improvements
Vertex Normal Performance
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.
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.
Form Workbenches
Workbenches are areas of the UI where tools, commands, scripts, presets, kits, channels, and macros can be grouped and organized. You can also make any form in Modo editable directly in the UI.
Item Notes
A Notes section has been added to the Item Properties. The description and comments added here are displayed as tooltips in both the Items list and the 3D viewport. The Items list can now be filtered based on the notes associated with items.
Modo Markup
Modo's text markup feature that allows you to add formatting to tooltips.
UVing
Transfer UV Positions
The Edit UVs Transfer UV positions option has been improved. In our prior versions, transferring UVs from one object to another identical object, you could only transfer one UV island at a time even if the object was continuous. Now the tool transfers all UVs of connecting polygons to the destination.
UV Box Transform Tool
New Gaps and Gaps By Pixel options have been added to the UV Box Transform direct modeling tool to allow you to add pixel border padding to your UV islands. You can manipulate the size of the gaps by using the box handles in the UV viewport.
Rendering
NVIDIA® OptiX™ Denoiser
You can now use NVIDIA's OptiX Denoiser for denoising render outputs on supported systems (Windows and Linux systems running NVIDIA GPUs).
3D Viewport Improvements
Display Subdivision Weight
Modo now displays the weights of Subdivision weight maps the same way as regular weight maps when the Show Weightmap option is enabled in the 3D viewport settings.
Show Locked Mesh Items
You can now see locked mesh items easily in the 3D viewport. By default, the new preference Show Locked Mesh Items option is enabled. Selected vertices, edges, or polygons on a mesh item are displayed in a specified color. When loop selecting or using other selection methods, locked elements are not selected. Changing the color of the locked elements, is done in the Systems > Preferences > Display > Color > PSUB Mask settings.
Feature Enhancements
• ID 311221 - UV Connectivity mode has been added to the UV Paste command.
• ID 341337 - Modeling: A Deform Space option has been added to Selection Action Center and Action Axis Selection.
• ID 346181 - UV: The Set Gaps by Pixel option has been added to have old gaps scope as an option. This fixes oddly positioned UVs.
• ID 355811 - Render: Modo's performance during sampling of an image in ray evaluation has been improved.The limit on the number of UV render outputs has been increased, limit checking has been added, and the UV output index is now reset to zero.
• ID 366043 - UI: The Animation Toolbar has been revised. The Spacing Chart and Inbetween buttons have been moved into the same row as the Dynamic Parenting and Motion Path buttons.
• File I/O: -import, a command line argument for adding session-only config paths has been implemented. It takes a path, dir or config file, which is added as a new session-only import path in the config system. The path is not written to the config on quit, and directories are not created if they don't exist yet. This is used like any other import path, in that configs are loaded from it and scripts can be launched from it.
• Preset Browser: ClipChoice has been converted to PBView and clips synthetic.
• Procedurals: The EdgeToCurve command now takes a poly type arg, or guesses based on the underlying geometry type.
• Scripting: The pure UI mode for user.value commands has been added, set through user.def uiMode, which supersedes the old asUI property, although that is still supported for backwards compatibility (uiMode takes precedence, if present). undoModel, undoUI and pureUI modes are supported.
• UI: ?min/?max query operator support has been added to numeric edits via text hints and UI hints.
• UI:Access to viewport options from tabbed viewports with their tabs hidden has been made easier. The Viewport Properties menu in a tabbed viewport now shows the settings for the current tab instead of being disabled. The Viewport Properties have been mapped to the O keyboard shortcut globally. This triggers the Viewport Properties menu for any viewport under the cursor.
• UI: New Dynamics and Particles toolbars have been added to the layout.
• UI: Icons and text labels on buttons have been shifted up one pixel (non-GL). This generally improves center of text and icons in faces.

• ID 366009 - UV: The Pack UV tool's Pack Region options kept resetting to default.
• ID 366134 - Modeling: Converting Edge selection to Polygon selection didn't always work as expected.
• ID 366297 - UV: Texel density kit incorrectly accounted for 3D size when sampling.
• ID 366385 - UV: Looping select UV Seam that bordered a split edge caused Modo to crash.
• ID 366476 - UV: The UV Box Transform tool's Snap Distance option ignored the zoom level.
• ID 367026 - Modeling: Random crash related to edge tracking.
• ID 368667 - Procedurals: The Clone Effector handled vertex selection incorrectly.
• ID 369125 - Modeling: The handles of Bezier curves imported from Illustrator could not be edited correctly.
• ID 369171 - UV: Zooming in and out with the scroll wheel in the UV viewport caused Modo to crash.
• ID 369447 - UV: The UV Box Transform snapping overrides constrained proportions.
• ID 369788 - Procedurals: Slice sometimes left a vertex floating in space when cutting a curve into two parts.
• ID 370148 - UI: Dragging the Render Camera label from the Render Item form caused Modo to crash.
• ID 370375 - UV: Copying and pasting an edge selection with UV connectivity caused Modo to crash.
• ID 370380 - Modeling: Removing an item while Geometry Snapping was enabled in the Toolpipe caused Modo to crash.
• ID 370597 - Modeling: A specific n-gon Bevel left one vertex behind.
• MeshFusion: Command Help for user values driving various popup menus were missing. A minor config issue was preventing some icons from displaying in the Fusion Item’s Properties.
• Particles: Exotype for Texture Particle size was a float instead of a distance.
• Preset Browser: Saving some presets didn't create a new directory (important for user paths from the Preset Browser).

• Procedurals: The Material mesh operation was much slower than the Assign Selection Set mesh operation.
• Scripting: The wrong notification flag was sent for the command enable set on a user value.
invert enable command test has been added for user.def, which inverts the results of the test for the enable command. This allows the user value to be enabled when the enable command is disabled and visa versa.
• Shader Tree: Changing material surface normal properties affected the wrong item in a specific scene.

Known Issues and Workarounds Specific to this Release
This section covers known issues and gives workarounds for them, where appropriate.
Note: Due to internal bug-logging and tracking process improvements, new bug identification numbers are used, with the legacy IDs provided in parentheses, where appropriate.
Animation
• ID 240321 (53661) - Selecting actions does not always select the correct one. This is caused by copying actions.
As a workaround, manually edit the tags on the broken actions by selecting them in the Groups tab, then save and reload the scene.
Assemblies
• ID 288164 (36452) - Assemblies exported from the Item List context menu result in poor visual layout of nodes on import.
As a workaround, you can save assemblies from the Schematic viewport.
Baking
• ID 355201 - Baking SurfaceID is giving different outputs. A bug has been fixed where deleting or disabling visibility of a mesh would change the SurfaceID colors of other meshes. The process is now deterministic, but the SurfaceID colors differ from previous versions.
• ID 293020 (50671) - Baking displacement maps can cause UV seams to be visible, and the baked displacement map to show quilting effects and other render artifacts.
• ID 221481 (49437) - The Bake Channel Swizzling option can’t bake to texture alpha.
Color Management
• ID 221439 (49244) - (Windows only): With Perform Color Correction on, setting a default scene to a scene with a mesh that has a position channel crashes Modo at launch.
As a workaround, use System > Reset Preferences to reset to defaults or move/remove the default scene.
Command Line
• ID 289290 (49514) - macOS X only: Running modo_cl before running the UI Modo application breaks code signing.
As a workaround, start the UI version of Modo once, before running modo_cl on any system where you later intend to use the UI version.
File and Image I/O
• ID 337523 (56862) - Modo for SolidWorks Kit: Modo crashes when importing the same SolidWorks file twice in one Modo session. This bug only affects import using the kit, not direct imports (File > Import).
As a workaround: Before importing a SolidWorks file for the second time, exit and restart Modo.
• ID 221508 (50198) - Alembic scenes don't export some surface items, including static meshes and procedural shatter items.
• ID 226589 (49728) - Exporting selected layers (from the Item List context menu) to .fbx doesn't export instances, unless the original mesh is also exported.
To resolve this, set the .fbx preference to Export Selection and use Export As….
• ID 220991 (47036) - Color management in .svg images is not currently supported. This is a side-effect of a bug fix where the largest allowable image size (64k x 64k) was always used when color correction was enabled.
• ID 220975 (46962) - Rendering .svg images used as stencil maps for displacement or for layer masking can be very slow.
Fur
• ID 288248 (35731) - Fur length textures can’t be edited with the Stretch tool.
As a workaround, use different fur length drivers, such as hair guides or vector vertex maps.
Input Devices
• ID 303287 (35856) - Linux only: Plugging in a Wacom tablet while Modo is running can cause undesired movement. This cannot be fixed, due to a limitation of the hardware driver.
To avoid this, plug in the tablet before application start-up or restart.
• ID 226536 (51741) - Mac OS X only: Modo sometimes becomes unresponsive when using the combination of a click-drag in a tree view (for example, when toggling the visibility of two successive items in the Shader Tree), followed immediately by a two-finger scroll gesture on some devices, including laptop trackpads and the Magic Mouse.
As a workaround, change to a 3-button mouse (recommended to fully access all of Modo's features).
MeshFusion
• ID 364399 - Outputting an Airtight Final mesh may flip some polygons.
As a workaround, select the polygon in Polygon mode and press the F key or convert the mesh to SubDs or PSubs (Tab or Shift+Tab).
• ID 316276 (56973) - If a Trim Fusion role is assigned to an object and then it is dragged and dropped onto a Primary, the drop menu does not contain the Trim boolean options.
As a workaround, use either the Fusion buttons (Tool palette - Set Mesh Role & Apply section) or Pie Menu (Apply Subtraction or Apply Intersection) when initially adding Trims to each Fusion Item (Trims can contribute to multiple Fusion Items). If initially applied with either of those methods, all subsequent Drag & Drop options will be supported.
Modeling
• ID 226970 (32728) - Zooming out with a Space Navigator alters the Work Plane position.
Network Rendering
• ID 226363 (48325) - Scenes with image sequences rendered with Full Frames use the wrong image sequence number on worker machines.
As a workaround, use File > Consolidate Scene, then render the scene using a shared network folder (Preferences option under Rendering > Network Rendering).
• ID 226337 (36986) - Workers render hidden meshes. Since mesh hide state is not stored in the scene, when that scene is transferred to the workers, the state is lost. The master respects the hidden state, however.
As a workaround, if the intent is to avoid rendering, toggle the visibility for the item or render or open System > Preferences > Rendering and disable Use Network Render Nodes.
• ID 226336 (25636) - Frame passes are not supported.
• ID 220955 (30318) - Network Rendering doesn’t support Realflow particles.
• Several Bugs - While it apparently worked in Modo 902, in some cases, Network Rendering was not implemented to support baking. Changes to Modo in the 10-series apparently broke what was working for some artists, so the functionality has been disabled.
As a workaround, Modo 10 implemented the ability to Network Bake using Bake Items and an external render controller. For more information, please see the SDK Wiki.
Nodal Shading
• ID 221393 (50642) - Nodal shading does not support UDIMs.
Painting/Sculpting
• ID 288461 (41682) - Textures are not always updating in Preview/Render when painting on an image map.
You can save and reload the image to force the update.
Particles
• ID 303192 (34925) - Re-opening scenes saved with large particle caches can cause problems.
To avoid such issues, delete the cache before closing Modo, or export the particles to .csv cache files or Realflow .bin files. You can do this by attaching one of those nodes to the Particle Simulation item in the Schematic viewport, and clicking Cache Simulation.
Preview
• If a high poly mesh is not visible, the Preview baking output will be incorrect.
As a workaround, reset Preview to fix the baking.
Procedurals
• ID 305303 (56318) - Procedural duplication of Mesh Ops in a Deform folder creates errant Mesh Ops list.
• ID 305302 (56317) - Duplication of Procedurals does not work with the Select By Previous Operation tool.
As a workaround, manually edit the duplicate's Select By Previous Operation Mesh Ops.
• ID 266469 (54738) - A duplication of any item that is a Merge Meshes Source (For example, a Mesh Item, Procedural Item, or Fusion Item), any duplicates (duplicate or instance) are added to the Merge Meshes Ops List as a source.
As a workaround, remove the unwanted additional Merge Mesh Sources (regardless of the type of source) in the Mesh Ops List using the X icon in that list next to each Merge Meshes source.
• ID 221355 (52149) - Curve Extrude mesh operation: The Path Segment Generator's Align to Normal option doesn't work when using a Bezier with zero-length tangents.
As a workaround, rotate the polygons to point toward the +Z before extruding or make sure there are no zero-length tangents.
• BUG ID 289810 (46512) - When rigged, Rock items and other procedurals do not display correctly in GL. This is a limitation of the feature and will not be fixed.
You can use Preview or RayGL to visualize the variations from rigging.
References
• ID 294394 (44492) - If a scene that already contains references is referenced, the shading of the original references may not persist.
As a workaround, limit scenes with shading to one level of reference.
• ID 220957 (41119) - Reloading a reference after replacing it with the same file can cause Modo to crash.
• BUG ID 309252 (56620) - Modo crashes when closing a scene containing a referenced scene after attempting to revert a reference override.
As a workaround, first close and reopen the scene before attempting to revert the reference.
Rendering
• ID 297021 (52730) - The Vertex Illumination Bake command doesn't work as expected, when the mesh has transform channels.
As a workaround, freeze the transforms in the mesh properties.
• ID 292947 (53184) - Value presets created for material Subsurface Scattering samples in Modo 10.1 or earlier now show on the render item instead.
• ID 279848 (55663) - Motion Blur applied on a curve in a mesh operation no longer works.
• ID 243070 (53793) - Rendering using a Dual CPU with 72 threads was significantly slower than expected.
As a workaround, any machine that has more than 32 cores, performance will be better if you limit rendering to half the number of cores you have.
• ID 235368 (53411) - Mesh lights or any direct light too close to a surface can produce fireflies (hot pixels) in some cases.
As a workaround, use a Maximum Radiance higher than 1 W/srm2 to reduce the bias.
Rigging
• ID 287584 (27244) - Duplicating joints in a bound mesh retains influences from the original joint chain.
Scripting
• ID 242545 (53458) - Right-clicking or running a script in the Script Editor can lock up input to Modo.
As a workaround, click in the top window of the Script Editor, use the main menus, or change to another application, then switch back to Modo.
Shader Tree
• ID 336112 (57874) - Custom Materials that define their own smoothing properties (such as the Skin material), no longer smooth the mesh correctly.
• ID 299187 (37858) - In the Shader Tree, choosing a group from Add Layer > Image Map > (use clip browser) fails.
To work around this issue, in the Clip Browser, choose a single image instead of the group, and then change to the image group using the Texture Layer's Properties tab.
• ID 288141 (30947) - Layer masking displacement does not work unless you drag and drop the masking layer onto the displacement layer.
Unreal and Unity Materials
• ID 295862 (50700) - There is no way to visualize the Unreal SubSurface Color effect in Modo.
• ID 294747 (50701) - Unreal material Ambient Occlusion does not bake correctly in Modo.
• ID 221477 (50451) - On some graphics cards, Unity material may cause flickering in the Advanced viewport when used with bump maps and shadows.
UI
• ID 333249 (57715) - Selecting items in the viewport does not always update the Properties form.
As a workaround, press the Alt key.
• ID 288714 (43162) - Windows only: Setting a custom text size affects Modo's text drawing.
As a workaround, go to the compatibility settings by right-clicking the Modo shortcut or executable, and turn off font-scaling for the application.
• ID 281374 (55759) - Transforming objects can cause the Items Properties panel to flicker.
• ID 277244 (55571) - Resizing the dopesheet in Zen crashes Modo 11.1, but not in Modo 11.0.
• ID 273139 (55185) - Text in the viewport icon buttons is not visible in the Advanced viewport on some macOS/AMD configurations.
As a workaround: Upgrade macOS to 10.12 or 10.13.
• ID 226492 (44496) - macOS X only: Disabling Affect System Color Dialog in Preferences > Rendering > Color Management, and using the system color picker caused colors to darken with each use of the color picker.
This is due to an OS X issue, which requires the color profile in both the monitor settings and color picker to be set to sRGB IEC61966-2.1.
• ID 224169 (44896) - Dragging and dropping an image from disk into the Clips list doesn’t work.
If the Clips list is empty, drop the image onto the bar at the top, otherwise drop it above or below other images in the list.
Viewports
• Windows only: Using Raptr can cause GL driver crashes in Modo.
• RGBA textures only draw correctly in the Advanced viewport. In the Default viewport, any unsupported texture effect on an image map is drawn as diffuse color when the layer is selected in the Shader Tree.
• ID 338599 (57955) - Clicking on the VR layout tab may crash when using a system with a Radeon WX-series graphics card. This is due to a driver bug and should be fixed by a AMD in a future driver release.
• ID 338374 (58003) - Game Navigation mode (camera rotation) does not work in a floating 3D view (palette or separate window).
As a workaround, use Game Navigation mode only in docked 3D views (views that are part of a Layout).
• ID 310930 (56706) - Unity and Unreal materials are not displayed correctly when first loaded into the Advanced viewport.
As a workaround, enable and then disable the visibility of the Shader Tree textures.
• ID 296123 (46995) - Ambient Occlusion display in the Advanced viewport is affected by selected item wireframes.
You can disable Show Selection in the Visibility options or disable wireframe drawing on the active mesh layers.
• ID 289738 (49473) - Projections are incorrect if the projecting camera is set to Vertical film fit mode and the width is less than the height.
• ID 289020 (43771) - Camera projections from non-render cameras show distortion in GL and baking.
To avoid this, make sure that the projection camera has a film width-to-height ratio that matches the main render camera.
• ID 281365 (55816) - Wireframes are washed out on transparent surfaces in the Advanced viewport.
As a workaround, avoid transparency when modeling or doing work where wireframes are needed. Alternatively, use the Default viewport.
Developer Notes
• ID 356825 - SDK: TDSDK Vertex and Edge classes didn't use the correct IDs for equality comparisons.
• ID 363748 - SDK: In some situations, the per_item callback was not called. (See this discussion: http://modo.beta.thefoundry.co.uk/forum/topic.aspx?f=11&t=25223)
• ID 364335 - TD SDK: The same vertex ID was being used repeatedly when trying to set disco UVs.
• SDK: SDK methods StripRichText(), to remove rich text in a string, and StringLookup(), to get a string from a string table have been added.
