hi all guys, I have questions about a problem that grips me.
I made this model in Zbrush, after which I created a Reto in Maya and finally uv mapped.
After that I exported the parts of the model in OBJ to keep the UVs, now I am creating polygroups on zbrush however, when I try to export the parts to bring them back to maya (to see if the uvs are working) half of them splits (I have also disabled the Grp key in texture)
where exactly am I wrong, any advice?

EDIT:
Basically I think I understand that the problem is the UVs dublicated on top of each other,
to solve I don’t have to overlap them?
