USD Editor

Quick Start

Use this skill for minimal, text-level USD or USDA edits and command-line USD inspection, conversion, packaging, rendering, and validation. Keep the change small and preserve existing composition unless the task explicitly says otherwise.

When authored Reality Composer Pro or USD content owns the scene, geometry, transform, animation, or material, keep that authored surface as the source of truth. Use Swift and RealityKit to load or adjust runtime state; do not recreate authored USD content in Swift unless the request is explicitly procedural.

If Swift code needs to open, edit, observe, or export stages in-process with USDStage, USDPrim, or USDLayer, switch to $usdkit-runtime-developer.

If the change is material- or shader-specific for RealityKit, prefer shadergraph-editor.
