Yes I know, however thats not the issue. If you look at the video I linked, the cage of the mesh deformer starts to increase (because of the pressure) but the original sphere doesnt move until the last frame.
I was playing around trying to fix it, thats why its set at 26, but the same issue persists.
I'm starting to think my GPU doesnt have to power to do it and I have to find another way. Is it the same way as in the video for you?
Edit: When I dont use a mesh deformer, there is no issue, I might just do it that way, but I was still interested in knowing what causes the problem.
