One particular Alembic import is skipping frames

Hi guys,

For some reason, alembic is skipping animation for only this particular geometry (attached gif). Other alembic caches are playing fine.

Look at the eyes getting stuck and then continuing. The head is also alembic but playing fine.


Reimported into 3ds max to see if the alembic export had a problem. Nope it plays fine in 3ds max

Somehow this is happening while importing into unreal.

So, I found a work around this by using GeometryCacheABC which allows streaming of alembic in sequencer.

Although, GeometryCacheABC doesn’t work in UE5, it crashes after playing a few frames, seems like it keeps stopping to evaluate every frame and not cache it like UE4??
