andy_vs How fast are we talking? Is it still within the bounds of physical reality?
Inertial damping will help you here (zTissue node)
Simple animation, first a few sec tiger walks, then runs. During a few seconds everything looks nice (except local surface trembling), then the tiger runs with jumps - and skin dives into muscles (Zbones) on some places. Ztets is much more detailed than on screens before. ColisionPointSurf 0.002 / ContactStiffnessExp 1x10*10 / Substeps 5
Scene and Ziva setup is 24fps.
Unfortunatly I have no screen right now, but I think it should be clear.
I would think it happens cause mesh (distance between skin and fascia) is thick in someplaces, but it doesnt look so thick during slow motions.
