100.3: Hotfix

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
