I have quite a fast moving animation, character dropping to ground.
I made the muscles and bones, all bone object.
created a tissue out of mesh
closed open edges(does not freak out now)
attached cosntraints to end of arms, and legs.
Ive got my mass down around 100.
collsion points 0.01
sub steps 5.
youngus modulus 106
surface tension 45
keyframe over 5 frames both of those from 0 to 1 on the ztissue
rest scale 1
contact stiffness 107
it seems to move ok with the muscles and bones as I slow animated from the first frame upwards,
but when it drops all hell breaks out. the skin doesn't follow or seem to collide with the muscles, not sure why.
