New Features

Animation and Rigging

Markup

The Markup tool allows you to draw directly onto selected camera views so you can add annotations, notes, and comments to your animations or stills.

Direct Modeling

Bevel Enhancements

Unbevel

Unbevel collapses beveled faces between two selected edge loops.

Add Point Option for Edge Relax

This option allows you to insert new points or remove existing ones along selected edges. 

Edge Chamfer Enhancements

• Profile Preset Support - You can now select a 1D profile shape to determine the shape of the chamfer.

• Reverse Direction - When using a profile preset, this option allows you to reverse the start and end of the profile curve.

• Reverse Depth - When using a profile preset, this option allows you to reverse the depth direction of the profile shape.

• Falloff Support - Edge Chamfer now supports falloffs.

Face Slide

The Slide tool has a new Face mode, which allows you to slide a vertex on a connected face.

MeshFusion

Surface Strip Embossing

A new workflow that allows you to create embossed surface strips on Fusion Items using simple, Bezier, B-Spline curves, or text.

Procedural Modeling

Mesh Operations

You can now create vertex maps and set weight values, seams, and RGBA values procedurally. The following tools are now available as mesh operations:

• Create Vertex Map

• Set Weight

• Set Edge Weight

• Set Seam

• Set RGB

• Select Vertex Map Value selection operation

Shading and Rendering

mPath Improvements

• Light Path Expression names have been simplified, making it easier to work with them in the Shader Tree.

• mPath now supports the rendering of AxF materials.

Scale Groups in the Shader Tree

Manually scaling individual texture layers in the Shader Tree may be difficult. The separate layers might not contain the same relative scale or tiling, which means you have to figure out what the relative scaling is. These parameters allow you to scale all layers within a material relative to one another in the Shader Tree.

Topology

Transparency Overrides

The X-Ray and Ghost 3D viewport transparency modes have been added to help you differentiate between background and foreground wireframes, so you can easily understand the topology you're working with. This option is especially useful for decluttering heavy wireframe models.

UV Enhancements

Unwrap & Relax

The Unwrap & Relax tool combines the Unwrap Tool and UV Relax into one tool, allowing you to perform two operations on your UVs in one step to create a UV pelt.

UV Relax Enhancements

The Ignore Edge Selection option has been added to the UV Relax tool. UV Relax is frequently run after Unwrap, which requires edges to be selected. You then need to drop the tool before running UV Relax. When this option is enabled, the UV Relax operation ignores any currently selected edges.

Workflow and UI Improvements

• Select Partial for Lasso Selection - The Lasso Partial Selection Mode (keyboard shortcut: 8) allows you to select entire edges or polygons by only selecting part of it.

• Always Raycast Option for Element Move - This option allows you to manipulate polygons in in Wireframe viewport mode. When disabled, only vertices and edges can be edited in Wireframe mode.

• Use World Transforms option for Falloffs - This option allows falloffs to affect all selected mesh surfaces as one surface and deform them as one. This option has been added to the following falloffs:

• Linear Falloff

• Cylinder Falloff

• Radial Falloff

• Noise Falloff

• Path Falloff

• Lasso Falloff

• Image Falloff

• Rename Vortex Deformer to Twist - Vortex Deformer has been renamed to Twist Deformer.

• No Trackball Rotation by Default - Trackball Rotation is now disabled by default for all viewports.

• Numeric Command Queries on Key Assignments - Support has been added to numeric arguments in the input remapping system.

Feature Enhancements

• ID 410657 - File I/O: Decimal frame support has been added to Alembic animation export, so fractional frame ranges can now be exported correctly.

• ID 417075 - Viewports: The Advanced viewport now supports color remapping, enabling non-default high and low texture values to be displayed correctly.

Advanced Viewport Improvements

• Support has been added for the Shader Tree Texture Layer’s Brightness and Contrast controls.

• Support has been added for Widget and UI element-wide line rendering.

• Added support for OpenGL Storage Shader Buffer Objects (SSBO). Extends storage and texture allocations for supported GPU drivers (not MacOS).

• Extra GPU information has been added to the viewport timeline when using the 'glmeter true true' command.

• MacOS HDR capable rendering (Experimental) has been added.

Known Issues and Workarounds

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 423909 - Markup: Setting image type to .jpg results in a black fill over the screen.

• ID 395357 - Deformer Caching doesn’t work as expected.

• 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 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.

Bucket Render

• 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.

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 346842 - Alembic import: Drag-and-drop doesn't import animation correctly.

As a workaround, use File > Import.

• 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 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 are supported.

Modeling

• ID 408278 (60027) - Linear Falloff snaps to the object size.

As a workaround, use the right mouse button for an interactive initial linear handle.

• 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 385250 - Nodal Shading is slower in 13.0 with some modifiers.

• 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 388978 - Paving doesn't work when a Guide curve runs through a paving hole.

• ID 305303 (56318) - Procedural duplication of mesh operations in a Deform folder creates errant Mesh Ops list.

• ID 305302 (56317) - Duplicating 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 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.

• 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 button 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.

References

• 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.

• 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.

Rigging

• ID 404238 - Bezier Curves don't work correctly with the Curve Falloff.

• 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 372282 (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 395884 - macOS only: Double-clicking the bottom right corner or edge of a popover doesn't resize the popover correctly.

• ID 388937 - macOS only: UI form field highlights occasionally appear solid gray.

• 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 497416 - The Gradient texture layer renders incorrectly in the Advanced viewport.

As a workaround, use Preview.

• ID 420733 - Ghost Mode Transparency set to 0% isn't fully transparent.

• 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.

VR

• ID 218386 - VR is now supported on Linux, but has only been tested and verified working using SteamVR on Ubuntu 18.04.
