2. Triggers renderingEventStream::pump

enumerator eUsdTimelineStateRefresh

Applies pending Timeline state changes.

enumerator ePythonAsyncFutureBeginUpdate

enumerator eOmniClientUpdate

Run OmniClient after python but before main simulation.

enumerator eUsdTimelineUpdate

ITimeline wants to execute before eUsdContextUpdate.

enumerator eUsdContextUpdate

Core UsdUpdate execution.

1. Update liveModeUpdate listeners

2. triggers stageEventStream::pump

3. MaterialWatcher::update

4. IHydraEngine::setTime

5. triggers IUsdStageUpdate::pump (see IUsdStageEventOrdering below)

6. AudioManager::update

enumerator eUnspecifiedUpdateOrder

Default update order value.

Note

extras::SettingWrapper is hardcoded to carb::events::kDefaultOrder which means this is when during the main update cycle, event listeners for settings changes events will fire. There are a minimum of 60+ unique setting subscription listeners in a default kit session.

enumerator eUIRendering

Trigger UI/ImGui Drawing.

enumerator eFabricFlush

enumerator ePythonAsyncFutureEndUpdate
