USD Optimize v1.0.3

[1.0.3] - 2026-05-28

Fixed

• FitPrimitive: no longer incorrectly fits a cube primitive to hollow meshes (e.g. an extruded box). Such meshes are now left unchanged instead of being replaced by a solid cube.
• Remove primvar indices when removing primvars.

Added

• Accept JSON int literals for float/double attributes.

Changed

• Bumped repo_usd to 5.0.34.
• Use symlinks for Python files where possible during builds rather than copying them.
