sounds interesting. Every time I think of “volumetric” soft body physics, something like Weta Digital’s “Tissue” system comes to mind. Simulating muscle and fatty tissue over bone, and skin sliding over all of that, etc. So that would be my first question, can layer soft body materials, including layering them over rigid bodies.
Then I’d want to pull off slicing of those volumetric characters for wounds(and worse).
Probably too much to hope for in a game
