I’m using zbrush 3.1 still.
I exported my model to fix my model’s UV map in Maya 2009, but when I reimport it again to Zbrush, it keeps blowing up.
I’ve tried exporting from zbrush with merge uv selected. I’ve also tried exporting with groups selected.
In maya I’ve tried to export with groups on and off, neither seem to be working. It keeps blowing up!
I’ve even tested doing all this without even playing around with my UVs, but I’m pretty confident you’re allowed to move UV’s around. I haven’t added any faces or any geometry to my model at all when re importing to zbrush. So not sure whats going on here.
