omni::usd::StageEventType

Defined in omni/usd/UsdTypes.h

enum class omni::usd::StageEventType

Defines the usd event types.

Values:

enumerator eSaved: USD file saved.

enumerator eSaveFailed: Failed to save USD.

enumerator eOpening: USD stage is opening.

enumerator eOpened: USD stage is opened successfully.

enumerator eOpenFailed: USD stage failed to open.

enumerator eClosing: USD stage is about to close. This is a good opportunity to shutdown anything depends on USD stage.

enumerator eClosed: USD stage is fully closed.

enumerator eSelectionChanged: USD Prim selection has changed.

enumerator eAssetsLoaded: Current batch of async asset loading has been completed.

enumerator eAssetsLoadAborted: Current batch of async asset loading has been aborted.

enumerator eGizmoTrackingChanged: Started or stopped tracking (hovering) on a gizmo.

enumerator eMdlParamLoaded: MDL parameter is loaded for a MDL UsdShadeShader.

enumerator eSettingsLoaded: Stage settings have loaded.

enumerator eSettingsSaving: Stage settings are being saved.

enumerator eOmniGraphStartPlay: OmniGraph play has started.

enumerator eOmniGraphStopPlay: OmniGraph play has stopped.

enumerator eSimulationStartPlay: Simulation play has started.

enumerator eSimulationStopPlay: Simulation play has stopped.

enumerator eAnimationStartPlay: Animation playback has started.

enumerator eAnimationStopPlay: Animation playback has stopped.

enumerator eDirtyStateChanged: Dirty state of USD stage has changed. Dirty state means if it has unsaved changes or not.

enumerator eAssetsLoading: A new batch of async asset loading has started.

enumerator eActiveLightsCountChanged: Number of active lights in the scene has changed. This signal should be triggered every time a scene has been loaded or number of lights has been changed. A few features, for instance view lighting mode, need to detect when a number of active lights becomes zero / become non-zero.

enumerator eHierarchyChanged: USD stage hierarchy has changed.

enumerator eHydraGeoStreamingStarted: Fabric Scene Delegate sends this when starting to stream rprims.

enumerator eHydraGeoStreamingStopped: Fabric Scene Delegate sends this when stopping to stream rprims.

enumerator eHydraGeoStreamingStoppedNotEnoughMem: Fabric Scene Delegate sends this when geometry streaming stops loading more geometry because of insufficient device memory.

enumerator eHydraGeoStreamingStoppedAtLimit: Fabric Scene Delegate sends this when stopping to stream rprims because of the limit set by the user.

enumerator eSaving: Starting to save stage.
