Hello everyone, I have a T-Rex walking animation driving by mocap using kinefx, no muscle simulation, here I find some mesh intersection because the difference between human and dinosaur. Is it possible to get rid of it, for example using some vellum tech? Thanks in advance!

that's pretty extreme intersetion and even if you solve it the movement and pose would probably look very unrealistic and probabaly with a loss of volume

I'd advise tweaking your retargetting to get better pose or also adjust with additional kinefx nodes or Rigpose after retargetting if needed

then, when you have pretty good motion and pose you can apply Delta Mush to fix some unnarural stretching and potential creases
or also do a vellum sim to resolve collisions

could you upload a hip file so we can see the skeleton?
