USD Optimize v1.0.4

[1.0.4] - 2026-06-12

Added

• Asset Validator parameters API: expose validator rule tuning so checker thresholds (e.g. OccludedMeshesChecker, SmallMeshChecker) can be configured via parameters.
• MergeMeshes: new spatial merge mode that welds coincident boundary vertices across seams.
• DeduplicateGeometry: new "Point Instancer" mode.
• PrunePayloads: option to avoid pruning unloaded payloads.
• DeduplicateHierarchies: support for nested instancing.

Changed

• Renamed Scene Optimizer to Usd Optimize.
• Validators now register against capability requirements (e.g. GeometryRequirements, HierarchyRequirements, MaterialsRequirements) via the new plugin entry point instead of rule categories.
• Migrated the asset validator dependency to usd-validation-nvidia.
• Reduced default logging noise across operations.
• Improved performance of PruneLeaves.
• Reverted repo_usd pin to 5.0.26 (restores the stock build; the 5.0.34 exchange build trimmed link deps).

Fixed

• DeduplicateHierarchies: fix value variant grouping.
• DiceMeshes: fix irregular multi-axis cuts.
• Fix gcc13 build issues from stricter compiler checks (DGX Spark defaults to gcc13).
• Replaced unsafe sudo/rm guidance in validators skill.
