Flesh Simulation Continued...

Continuing to refine the flesh/fatty tissue simulation using a new body type. This setup is now completely reusable, I only need to provide an animated interior and exterior mesh (boundary edges need to be coincident). There are only a couple of parameters that need to be tweaked to adjust the volume behavior. I'm getting closer to a result I like, particularly for the upper legs. This technique has the added advantage of fixing bad skinning...notice the hips and crotch area.

Next step is to try and bundle this up as digital asset and get in running inside Maya using Houdini Engine.

  1. Hi Grant! Great job!I have a couple of questions, Did you atach the boundary edges with constraints? and Did you use animated rest geometry of the flesh volume?

    thanks!

  2. Thanks Marcelo, and apologies for the extremely late reply!
    The boundary edges were attached using the fuse SOP, using a very small distance threshold. The sim was only constrained to the interior geometry.
    I've actually uploaded an example scene that you can dissect if you want to know how it was setup. Here is the link - http://bit.ly/2dB9T7D
