100.2 Hotfix Release Notes
- Features
- Add Unreal Engine 4.26 editor support
- Note: The export folder dialogs in 4.26 do not refresh Omniverse server folders properly. Browse/create folders from the Content Browser first.
- Bug Fixes
- Collision properly exported from stand-alone static mesh asset exports
- Fix crash when exporting DDS textures when a material uses virtual textures (note, proper VT export is not supported)
- Fix crash when loading Level with USD actors
- Fix live-edit of many Cinematic Camera properties
- Fix binding materials to geometry subsets, honored only if the familyName of subset is UsdShadeTokens->materialBind
- Remove the “Omniverse USD Sequence+ (usd)” Image Output Format from the Render Movie Settings because it is no longer supported
- Fix crash when importing USD skeletal meshes. Garbage collection cleans up StaticMeshLOD so some classes needed to be moved to a different module.
- Changes
- Avoid exporting TangentX array for skeletal meshes if unnecessary

100.3 Hotfix Release Notes
- Features
- Add support for MetersPerUnit on import and export for meshes, shapes, cameras, lights, and stages
- Bug Fixes
- Fix crash when editing material caused by Geometry Subset material binding
- Remove duplicate vertices when exporting UE4 Landscape to USD mesh
- Fix SkelRoot live edit perf issue
- Get full data and handle transform exporting from Level Sequence sections even if there’s no key in a shot
- Avoid crashing when MDL function call creation fails and reports an error
- SkyAtmosphere material expressions get a constant 0 value when exported as MDL
- Changes
- Always create UE4 actor when loading a USD prim (rather than only if it is a model or lacks a parent component). This changes the layout actors, meshes, components, etc in UE4 to be more like the USD stage. Fewer components, more actors
- Merge multiple camera sequence shots into a new USD camera while still preserving the original shot cameras
- Support exporting BC6H/BC7 2D textures
- Replace UE4 material function DeriveTangentBasis with TangentBasis when exporting MDL materials due to the usage of incompatible DDX and DDY material nodes
100.4 Hotfix Release Notes
- Features
- Add the optional OmniverseGroom plugin to 4.25 and 4.26. This plugin will export Groom assets as USD Basis Curves.
- Bug Fixes
- Fix crash when importing Black_Oak from mounted tree library. Do not attempt to reuse an actor of a different class.
- Fix a crash when closing the editor when connection to an Omniverse server had previously failed
- Fix a crash when opening an MDL that is referenced from a path larger than 260 characters (or so) due to Unreal Editor path length issues
- Fix a crash when exporting a Level Sequence actor with a shot in negative time
- Fix USD Skeletal Mesh animation importing and playing when triggered from within a Level Sequence
- Fix an issue where imported USD timesamples that changed visibility on a parent prim did not affect children meshes.
- Fix an issue where the Landscape default weight map was missing when DDS textures are exported.
- Changes
- Make basic USD shapes (sphere, cube, etc) use the same default material that meshes use when no material is bound
- Don’t allow deletes of ancestral prims from referenced USDs within a stage
- Support live replacement of mesh prim from point instancer with a UE4 static mesh
- Workaround issues related to materials that employ Parallax Occlusion Mapping (POM) since this doesn’t translate well to MDL
- Add support for the Black-body radiation material expression node with MDL
- Add primitive data (bounding box, etc) from Unreal Engine to MDLs through a custom expression
- Trigger Skeletal Mesh animation from within a Level Sequence rather then on the actor to ensure that animations with other actors are synchronized.
100.5 Hotfix Release Notes
Highlights
- C++ projects can now build properly if the are using the Epic Games Launcher source
- Fixes for Spotlight and Post Process Volume translation reported by the community
- Enhanced MDL translation support for more Unreal material expressions
Details
-
C++ projects can now build properly if the are using the Epic Games Launcher editor source
-
While we’re still working on releasing the plugin source, we have included the *.Build.cs files so that C++ projects are supported with the NVIDIA Omniverse USD and MDL plugins. This won’t yet work with the GitHub Unreal Engine source, but it will work with a project based on the Epic Games Launcher editor source.
-
-
Fixes for Spotlight and Post Process Volume translation reported by the community
- We improved the Spotlight to Sphere light translation and added mapping of the PPV’s “Exposure Compensation” to “cm^2 Factor” in the Tone Mapping RTX Settings in Create.
-
Enhanced MDL translation support for more Unreal material expressions
Complete changelog:
- Features
- Add the module *.Build.cs files to allow C++ source project builds using the Epic Games Launcher source
- Bug Fixes
- Materials
- Unify MDL export warnings so they all appear in the same message log whether exporting to local disk or Nucleus server
- Add a new way to identify if the refraction contained in material expressions can be used for MDL IOR. For example, if texture sampling is used to drive refraction attributes in a material, it will be ignored and replaced with the default IOR constant.
- Fix 4.26 fog volume MDL exports, the subsurface color attribute was incorrect
- Fix an issue with a missing override material when exporting instanced meshes
- Fix an issue where initial material creation and application on a prim in Create did not live-sync to Unreal Engine
- Fix MDL/texture importing when sampled with address mode (wrap vs. clamp)
- Fix translation of the Panner material expression node to MDL
- USD
- Fix a crash when exporting shots in a Level Sequence that end outside the time range
- Fix a crash by not allowing an imported Level Sequence actor to be renamed
- Fix a crash when editing the transform of an instanceable prim by locking the movement of an actor if it’s a descendent of an instanceable prim
- Fix USD warnings when reading incorrect value types
- Fix an issue where USD mesh shapes axis changes did not live-sync
- Lights
- Fix export of SpotLights to USD SphereLights (credit Alex Jenyon for notifying us of this issue)
- Fix the import of SphereLights as SpotLights to take the stage’s metersPerUnit setting into account
- Install
- Fix the uninstall to only delete files that were installed, not the entire folder where the plugins were installed
- Changes
- Materials
- Add annotation to MDL parameters so that DisplayName, Description, SortPriority, Group, and Range are all exported and visible in Create
- Add support for the clamped texture sample setting in the texture asset for MDL export
- Add support for the exporting the PerInstanceRandom material expression node to MDL
- Other
- Add a utility Blueprint function to list the contents of a Omniverse server folder (ListOmniverseFiles)
- Add support for exporting Level Sequence shots with the correct priority into a single Omniverse shot camera
- Support mapping a Post Process Volume’s “Exposure Compensation” to “cm^2 Factor” in the Tone Mapping RTX Settings in Create
- Add support for importing USD capsule shapes
- The defaultPrim on exported stages now have a blank Kind, rather than be set to “group”. This fixes some prim/defaultPrim selection issues in Create.
