USD for Maya v0.29.0 Release Notes
Release Highlights
Support for blend shape import
With USD for Maya 0.29, you can now import USD blend shapes into Maya blend shapes, while preserving all the attributes.
Upgraded transform manipulator with edit routing support
We have upgraded our system to include edit routing support for the transform manipulator. With this enhancement, you can configure the edit router to automatically write all the transformations into a specified layer whenever the transform manipulator is utilized.
Ability to copy and paste a prim
You can now copy and paste a prim in the outliner. The pasted prim will be a sibling of the original prim by default and will be selected upon creation. You also have the option to paste it as a child to another prim.
Improvements on export
- We have added the capability to exclude empty transforms when exporting USD.
- We have added the ability to export materials to USD without the geometry.
- When exporting geometry with materials, you now have the option to export only the assigned materials.
- We have improved the consistency of the USD prim hierarchy by standardizing how material scope is written.
Display of material attributes in the Attribute Editor
We have enhanced the attribute editor to include the display of a prim's assigned or inherited material information. You can also open the material in the LookdevX graph editor by simply clicking on the LookdevX icon located next to the assigned material field.
