USD Scene QC

Lightweight validation tool for detecting subtle issues in USD scenes before they impact rendering

Validates USD scene integrity by detecting inconsistencies in attributes, references, and render settings. It provides a simple way to scan a scene and surface issues early, before they become harder to track down. The tool integrates into Houdini workflows and can be used as part of a quick validation step before handoff.
