Hi all , i just export my bear ( 13k poly ) to 3dsmax to add UV, then import back to zbrush to do polypaint. But the program’s kidding me , it told me that the topology has change ( i just add uv , don’t do anything else ) ! And it want to reproject higher division. That maybe slow, and sometime come up with some fail areas. I dont want that , please tell me what exactly i’m missing ? thanks alot !
You need to check your export settings from Max - simply importing UVs should not result in a mesh change so you must have re-ordered vertices or something.
