Paul says to cache out the strands to 1 frame.. and read that frame back in for all frames.
If I cache out frame one, and read that in again right underneath in the ICE tree it works and deforms as expected without jittering - the groom node is still plugged in. However it is really slow at loading the cache and evaluating the ICE tree - I guess Cage deforming the strands is slow, and it crashes on the renderfarm - I can only render it in the UI on one workstation. If I attempt to export the butterfly as an Arnold .ass file Softimage is either really slow, or crashes. I suppose if I could cache the deformed strands, and load that cache, it would work. How exactly did you do when unplugging the groom node? I get weird results with the cage deform sort of mixing with the first frame which I cached out.
