So I redo the uv’s of my model in maya 2009. But when I try to import the new obj file(with the new uv’s) into zbrush, and going up to higher subdivs, the mesh explodes. I tried the same process with the default polysphere in zbrush and same thing happened, the mesh exploded when trying to go to higher subdvis. Has it something to do with the normals? Thanks for the help.
I have resolved my problem. I found the answer in another thread. Please close this thread, sir moderator. Thank you.
