Author USD Physics for ovphysx

This skill explains how to author a USD scene for ovstage to populate and ovphysx to simulate. ovphysx consumes an attached ovstage.Stage, not USD or the authoring tool's USD runtime directly. Build and save the scene first, use ovstage to populate an ovstage.Stage, call advance_write_floor() to seal the ordinal, and attach with attach_ovstage(). Drain later edits with update_from_ovstage(), and clear the stage with reset_stage(). See basic-workflow and docs/ovstage_integration.md for the populate/seal/attach sequence.

When to Use

Use this skill when you need to create or edit USD content that defines physics: a rigid body, a collider, mass properties, or the physics scene itself.
