110.4.0#

Release Date: October 2026

Fixed#

Optimize Materials

  • Materials that reference different files are no longer treated as duplicates when none of them compose any shaders, for example, MaterialX materials when the MaterialX standard library is not installed.

Performance Validators#

  • The ColocatedVerticesChecker fix now also removes the degenerate faces that welding creates.

  • PrimitiveFitChecker no longer offers a fix for meshes with non-constant primvars, so applying fixes cannot discard those primvars. Its message points to the Ignore non-const primvars option of Fit Primitives instead.

Updated#

  • The usd-optimize core package is now version 1.3.1.
