System Documentation

What problem does it solve?

Scene optimization changes large USD scenes in ways that are hard to verify by inspection, and you need a reliable before/after summary to confirm the optimization actually helped and didn’t break anything.

Core Features & Use Cases

  • Before/After Metrics: Computes a structured comparison of file size, prim counts, mesh counts, vertex/face totals, material counts, and instance counts between two USD stages.
  • Optional Validator Deltas: Diffs validator summaries (or CSV-derived totals) to show whether issues improved after optimization.
  • Optional Prim-Level Changes: Reports added/removed prim paths on request to help locate what changed in the stage structure.

Quick Start

Use compare-stages with two USD file paths to produce a before/after metrics report, optionally adding validator diffs with the --validators flag.
