100.5 Hotfix

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

  • 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.
