UV-less meshes are no longer imported with corrupt UVs.

Added support for exporting selected meshes/objects.

Fixed a memory leak that could cause a crash on Mac when downloading many assets.Selecting but not editing the path to a mesh file reference no longer causes a reload.The Subdivision Level setting is now retained when using PNTriangles and switching between modes.Fixed a crash that could happen when loading certain alembic files.Resolved an issue with stray vertices when sub-division is applied to animated, skinned meshes.Fixed a bug with the raster renderer that could cause renders to take twice as long when motion blur was disabled.Fixed a mipmapping error that could cause the viewport preview to diverge from the final exported textures.Fixed a problem with the brush tool that could cause a halo-like artifact when painting overlapping strokes with dark albedo values.

Clearcoat material values should now be read correctly on import.Materials are now created with the dither method during import if a transparency texture is found.Improved loading of missing textures in certain cases.Reflectivity is now disabled if not found in the material properties during import.Texture tiling settings are now retained when importing USD files into other applications (where supported).Fixed an issue with triangle winding that could cause inverted faces when reading USD files from certain applications.Resolved a problem with writing UV data that was incompatible with certain applications.Fixed a crash when importing USD files that contain vertex colors.Objects that have a single material assignment no longer are written with sub-meshes, which improves compatibility with some renderers.Optimized export time for dense meshes.Installers: Windows | Mac Import & Export USD Version 4.064 Hotfix | September 29th, 2023
