Mudbox mesh breaking apart

After I’ve worked on a mudbox mesh for a while (a couple hours, maybe) it often starts to break apart, like so:

I can sort of fix it with smoothing, but it’s a pain in the ass. At first I attributed it to GFX card overheating, something that’s given me trouble in other apps in the past, but I loaded this up right after turning on my PC and it happened right away.

Nevermind, question answered.

If anyone else has this problem, it’s just a viewport bug. The mesh is still in one piece.

Was you making an erect penis or something because it looks veiny?

That looks amazing!
