enumerator eOmniClientUpdate#: Run OmniClient after python but before main simulation.

enumerator eUsdTimelineUpdate#: ITimeline wants to execute before eUsdContextUpdate.

enumerator eUsdContextUpdate#

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.
