had the same problem:
just set rotate model; texture coordinates(if you did unwraping in max);quads or polygons(belongs how clean your mesh is. zbrush triangulates ngons automatically). other options have to be unset.
Thank you Guys.I suspected the problem had to do with exporting the .obj
mesh, but didn´t know what to do as you experienced fellows did.
Now I can hopefully ,aplly few wrinkles , spots and open pores on my model
and receive it back.Max has paint capabilities now , but no comparison possible with ZBrush.(The speed issues and tools)
Sorry I know How basic it was the question , but what a headache.:o
