Ive been working on a model in ZBrush and finally have exported it to Maya.
However the normal map Ive been creating in XNormal keeps coming out faulty everytime.
Anyone have any ideas regarding my workflow Im using or tips on things to try?
Definitely looks like a UV unwrap problem. You probably have some parts of the body/shoulders inside of the face, check your unwrap and you’ll probably see some overlapping.
I mean the normal map image maybe is inverted in the vertical.
If you have a unwrapped object, have rendered the normal map of the high poly and is using a object with the same uvs from the one you used to render the normal map and if you don’t have overlapping Uvs even with a ‘bad’ unwrap you should have the texture in the right place. A good Unwrap should have the less disrtortion as possible anyways. This is from a character of mine, I always do something like this:
The helpful posters above have selected the outer edges of each UV island. This highlights all edges, and so any holes (eyes or mouth) show up too. There is no need to ‘cut out’ the eye holes - this is already done, and I don’t know what extra you could do.
The general suggstion is that Zbrush commonly produces UV maps that need to be flipped (vertically) before they can be used in other DCC packages. Unless you specifically know that you checked for this, might be worth a look.
Other possible cause of your problem might have been overlapping UVs, but it looks like Zbrush did a reasonable job there.
Last thing I can think of is to make sure all your UVs are within the 0-1 tile (the first UDIM) for Xnormal. If it overlaps the boundary, that could cause funkiness. It’s difficult to tell from your screenshot, so worth a look.
Im mostly a Im originally a concept painter, and just learned 3D recently to model out the above head.
Do you think you could explain what you guys mean in simpler terms of what I could try to do
(And how to do it?
For ex. I have no idea what he means for me to do, like where do i even start? “Check the repeat and offset settings on the place2dtexture node.”)
Maybe something like…
You should try saving your file

The whole file is also available for download, incase you guys would want to try it out your theories as well.
