Timeline and Alembic Track Issue

I’ve found an issue in Alembic Track

Now that Timeline has Alembic Track, it should be default behaviour to update alembic animation state on calling

playableDirector.Evaluate();

Right now Alembic Stream Player updates only once per frame. But an ability to update more times via timeline is essential for consistency reasons.
p. s. This functionality is essential for Deckard Renderer motion blur that uses Multisampling, that gets rendered by rendering multiple frames with different time states.

Hey,

As of alembic 2.0.0 the AlembicStreamPlayer has a method called UpdateImmediately that does not defer the streaming until LateUpdate. Unfortunately the TimelineTrack does not use it. I don’t think updating upfront always would be the desired behaviour.
What sort of functionality would you expect ?
Would Update Immediately during an Evaluate and deferred during playback be enough?

If I understood well, yes, it should be OK. We just need that if timeline playableDirector receives Evaluate() call, it also sends each time UpdateImmediately (and animation position) to alembic track. This would work for our purposes, and it would be consistent with timeline Evaluate functionality.
This is essential for my clients, as many of them use Deckard for rendering Alembic animations.
