wish I was talking about meaning of life.
but really what I’m talking about is a fluid sim problem with animated objects and the fluid “anticipating” the impact with said object by several frames, reacting ahead of an impact. this was annoying.
well all my objects in the sims had been subsurfed. subsurf meshes were interacting at the cage level, not the visible 'surfed level, and that accounted for floating objects and improper fluids. (yuck).
this is probably useful to somebody.
