Release Notes#

110.3.1#

Release Date: October 2026

Added#

You can use a Temporal Combined input mode that samples every selected mesh across a time range and writes one static swept-envelope mesh.
You can control the sampled range and how motion between samples is filled with Start Time, End Time, Time Step, Connect Time Samples, and Output Path.

Edit Stage Metrics

You can use Stop At Skeleton Root to correct a skeleton at its SkelRoot rather than at every prim beneath it.

Move Materials#

Move Materials is available again. You can move all materials under a chosen prim path, for example /World/Looks.

Performance Validators#

You can tune parameters for CoincidingGeometryChecker, ColocatedVerticesChecker, FlatHierarchiesChecker, HighVertexCountChecker, PrimitiveFitChecker, RedundantTimeSamplesChecker, and RtxMeshCountChecker.

Fixed#

Undefined prims (pure over prims) no longer count as content, so a grouping prim is pruned even when a removed reference target left dead overs behind. Inactive prims are unaffected and remain controlled by Filter Inactive Prims.

General#

GPU-accelerated operations no longer fall back to the CPU under WSL. CUDA is now detected by loading libcuda.so rather than by checking for a PCI display adapter, which WSL does not expose.

Updated#

Updated the usd-optimize core package to 1.2.2.
