Internal_reference count of active OIT pipelines.
Register an active OIT pipeline. Sets RenderingState.transparencyMode
to 'oit'. Returns a release function that must be called when the pipeline is
disposed; the mode reverts to 'standard' once all registrations are released.
Reference counted so multiple/short-lived passes behave correctly.
The active transparency mode. Defaults to 'standard'.
Per-canvas rendering pipeline state.
Lets components react to which rendering pipeline (if any) is active without the user having to manually configure each component. The defaults match the behavior of default rendering with no custom pipeline.
