Is there an option for the solver to interpolate between alembic frames? For example, this frame doesn’t push around the fluid (this is an animated cylinder that wiggles up):
This is the same alembic using the FLIP fluids add-on in Blender showing the kind of behavior you’d expect:
I’ve attached two gifs to help demonstrate what I mean.
I’ve messed with a bunch of settings that sound like they might help this but I end up with the same result of the solver not respecting the motion of the alembic.
