    Hello!

    I'm generating a Normal Map in Zbrush. Model has been done in Maya, properly UV mapped and imported as an OBJ. NM generation seems ok in Zbrush but when I import the texture to either Maya or Unity I get some weird results. What I think is happening is that each Shell of UVs gets some weird channel flipping depending on the orientation of the Shell itself. The result is what I get in the image attached. I'm on a mac by the way, so no Zmapper or any of those PC oriented plugins or NM generation software :(

    Any help is appreciated!

    Nick.

    Hey, try to triangulate your mesh and do an edge flip on these faces. Works for us with Blender and Zbrush.

    I think you should flip the UVs on Zbrush

    The way to fix this is to go into zbrush open the texture pallet and select the texture. Then click "flip vertically" and it will solve the problem.
