What problem does it solve?
Deduplicating USD scenes manually is slow and error-prone, especially when repeated prim hierarchies bloat files and increase load time.
Core Features & Use Cases
- Hierarchy-level deduplication: Detects duplicate prim hierarchies level-by-level under the stage default prim and replaces duplicates with internal instanceable references to the first prototype.
- Safe matching by structure + property values: Uses subtree shape, prim types, authored property names, and property-value verification to merge only truly identical hierarchies (with tolerance for float-array and scalar float/double drifts where applicable).
- Pipeline-ready for production: Supports a canonical two-op workflow by pairing hierarchy dedup with per-mesh dedup to catch remaining identical meshes not folded at the subtree level.
Quick Start
Run deduplicate-hierarchies on your USD file by providing the full path to the asset and optionally restricting the scan to one or more prim paths.
