Stage Events are emitted when certain USD stage-related actions are performed by the system: Saved: USD file saved. Selection Changed: USD Prim selection has changed. Hierarchy Changed: USD stage hierarchy has changed, e.g. a prim is added, deleted or moved. OmniGraph Start Play: OmniGraph started. OmniGraph Stop Play: OmniGraph stopped. Simulation Start Play: Simulation started. Simulation Stop Play: Simulation stopped. Animation Start Play: Animation playback has started. Animation Stop Play: Animation playback has stopped.
