110.3.1

Release Date: October 2026

Added

Shrinkwrap

• 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

Prune Leaves

• 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.
