Elegant geo changes?
I had muscles with new topology, the script didn't flag it as new topology and it just assigned all the new verts to 100% on all attachments. If I get a moment, I could send you something for testing.
Builds with Collision Meshes?
I'll see if I can reproduce the problem on my end again. Thankfully for now, taking out Collision meshes and putting them back in is pretty easy.
Thanks for looking into it for me!
