3.1.0-usd.100.1.10
Support UDIM textures when importing USD Preview Surface shaders.
New “Material Name Collision” USD import option, to allow importing materials with duplicate names.
Added default values for the “Default Prim Path”, “Root Prim Path” and “Material Prim Path” export options.
If the “Root Prim Path” export option is set, the root path won’t be added if a Blender object matching the root name already exists.
Now aborting with an error if the root prim, default prim and material prim path export options are not well formed USD paths, to prevent crashes when defining prims.
Improved warning and error messages during UMM material conversion.
Support importing USD attributes (string, int, float and vector types) as Blender custom properties.
Property export improvements: support exporting vector types; provide options for setting the attribute namespace.
Enable operator presets UI for USD import and export.
Armature export improvements: fixed bugs causing skeleton bindings to fail; warning if the skinned prim and skeleton are not under a common SkelRoot; new “Fix Skel Root” experimental option to automatically correct invalid SkelRoot hierarchies.
Importing existing USD Preview Surface shaders as a fallback if importing MDL is selected as an option but the material has no MDL shaders.
Fixed bug preventing packed textures from being exported when exporting USD Preview Surface shaders.
Fixed bug preventing USD Preview Surface textures from being imported in some cases.
