New Features and Enhancements

There are no new features or enhancements in this maintenance release.

Bug Fixes

• ID 517772 - The Deadline submission kit (AWS/Thinkbox) did not work as expected in Modo 15, or later. This fix includes a Windows-specific fix to Python paths in Modo, which stopped the kit working.

Note:  Only those submitting jobs to a Deadline server using the Deadline Submission Kit on Windows need to install this update. All platforms have been updated to this version (v4) and build number (662987) so that mixed render farms can all use the same version, if desired.

Known Issues

This section covers known issues and gives workarounds for them, where appropriate.

Animation

• ID 423909 - Grease Pencil: Setting image type to JPG results in a black fill over the screen.

• ID 395357 - Deformer Caching doesn’t work.

• ID 240321 (53661) - Selecting actions does not always select the correct one. This is caused by copying actions.

Note:  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.

Note:  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.

Note:  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.

Note:  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.

Note:  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.

Note:  As a workaround, use System > Reset Preferences to reset to defaults or move/remove the default scene.

Command Line

• ID 289290 (49514) - macOS only: Running modo_cl before running the UI Modo application breaks code signing.

Note:  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/drop doesn't import animation correctly.

Note:  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 only affects import using the kit, not direct imports (File > Import).

Note:  As a workaround, before importing a SolidWorks file for the second time, exit and restart Modo.

• 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.

Note:  To resolve this, set the .fbx preference to Export Selection and use the Export As… option.

• ID 221508 (50198) - Alembic scenes don't export some surface items, including static meshes and procedural shatter items.

• ID 220991 (47036) - Color management in .svg images is not currently supported. This is a side-effect of a 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.

Note:  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.

Note:  To avoid this, plug in the tablet before application start up or restart.

• ID 226536 (51741) - macOS 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.

Note:  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.

Note:  As a workaround, use either the Fusion Buttons (Tool palette - Set Mesh Role & Apply section) or Pie Menu (Apply SubtractionApply Intersection or ) 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 408278 (60027) - Linear Falloff snaps to object size.

Note:  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 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.

Note:  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 226363 (48325) - Scenes with image sequences rendered with Full Frames use the wrong image sequence number on worker machines.

Note:  As a workaround, use File > Consolidate Scene, then render the scene using a shared network folder (Preferences option under Rendering > Network Rendering).

• 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.

Note:  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.

Note:  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.

Note:  To avosuch 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 Render

• If a high poly mesh is not visible, the Preview baking output will be incorrect.

Note:  As a workaround, reset Preview to fix the baking.

Presets

• ID 242621 - Assembly Preset Aliases will crash when certain connections are made to them. If any of these are inside of an assembly alias that is collapsed, then you can potentially hit a crash: Replicator Item, Array Operator modifier, Falloff Operator, Selection Operator, Particle Operator, Any kind of texture (images, procedural textures, etc)

Note:  As a workaround, expand the assembly alias, as evaluating those types of items for a non-aliased assembly should still work fine.

Procedurals

• ID 484639 - Select by Material Tag doesn't work with Mesh Op stack.

• ID 388978 - Paving does not work when a Guide curve runs through a paving hole

• 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.

Note:  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.

Note:  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.

Note:  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.

Note:  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.

Note:  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.

Note:  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 483457 - Disabling or hiding connections using the H keyboard shortcut causes the stack order to behave erratically.

• 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.

Note:  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 385991 (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.

Note:  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 - Mac only - Double-clicking bottom right corner or edge of popover doesn't resize back the popover correctly.

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

• ID 333249 (57715) - Selecting items in the viewport does not always update the Properties form.

Note:  As a workaround, click the alt key.

• ID 288714 (43162) (Windows only) -Setting a custom text size affects Modo's text drawing.

Note:  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.

Note:  As a workaround, upgrade Mac OS to 10.13.

• ID 226492 (44496) - macOS 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.

Note:  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.

Note:  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

• ID 478549 - Saving Alpha with Playblast is just completely white.

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

• ID 408416 - Gradient (texture layer) renders incorrectly in the Advanced Viewport.

Note:  As a workaround, use Preview.

• ID 310930 (56706) - Unity and Unreal materials are not displayed correctly when first loaded into the Advanced viewport.

Note:  As a workaround, enable and then disable the visibility of the Shader Tree textures.

• ID 338374 (58003) - Game Navigation mode (camera rotation) does not work in a floating 3D view (palette or separate window).

Note:  As a workaround, use Game Navigation mode only in docked 3D views (views that are part of a Layout).

• 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 and should be fixed by a AMD in a future driver release.

• 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.

Note:  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.

Note:  As a workaround, avoid transparency when modeling or doing work where wireframes are needed. Alternatively, use the Default viewport.

• 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.

• Windows only: Using Raptr can cause GL driver crashes in Modo.
