Does anybody know if there is a way to import a new UVW onto your existing sculpted OBJ file?
Basically, I realized that my UVW maps werewonky after I exported out my Normal map in ZBrush. What I’m hoping I can do is re-pelt the problematic area of my model and then add that new map to my already sculpted file to make a new normal map. Do you know if this is possible and if so how I should go about it?
Any advice is much appreciated!
very simple.
export out model from Zbrush at the lowest SubD.
(check tool>export> and turn “grp” off. It exports out the obj as each polygroup being it’s own element/island.)
import that obj into your unwrapper. (don’t change anything but the UV’s)
if you’re using max turn everything off but texture coordinates.
unwrap.
export (max - turn everything off but texture coordinates)
in zbrush, go to your lowest subD, store a morph target (incase size changes)
go to tool>import>grab new Obj with UV’s
step up subD’s to see if the mesh explodes…if not, you’re all set.
If it does explode, then somewhere in the import export process the point order was changed.
I’d just try it on a box or cylinder or something simple so you can get the feel of getting new UV’s in before you go and do the whole new unwrap and it doesn’t work.
Thanks! I’ll give it a try!
I figured out how to do it. I ended up using the Zprojector to project my textures onto my updated geometry and make new normal and cavity maps from that!
Thanks again.
