This is the issue I'm having when I try to paint weights, she basically explodes. The only reprieve I've found is to scrub through the animation a bit and it usually resets so that I can paint maybe one or two strokes before it explodes again and I rinse and repeat the process for each weight painting stroke(or 2).

However, as the video shows, this is what it does from time to time; where scrubbing doesn't reset it and the mesh either turns red, or green wire mesh only, or random rainbows. Really pretty, but very counter-productive.

Maybe someone has run across this before?

Any ideas?

Thanks.

Oh I tried exporting weights, new skin, import weights, and the same thing happens. FYI.
