Thanks. I can see why it refers to geo cache as ‘experimental’… I’m finding sometimes it works, sometimes not. Following your steps it did work - but when i reopened the sequencer it went back to static again. So doesn’t seem that stable. Currently having to move the mesh around to fit the jacket and fiddle with the frame rates, etc. I’m going to look into doing everything in maya and importing the whole lot as a single alembic now. Perhaps that’s a better way to go?
