Hello @Louxologic

I’m not certain what I’m looking at here. The image on the right appears to show a rear facing surface underneath the holes. ZBrush doesn’t support overlapping UVs. Those islands should be 2d geometry with nothing behind them.

It would also be useful to get a look at your UVs flattened in UV master so we can see how closely the islands are butting up against the boundaries of the UV space. ZBrush likes it when those islands have minimal contact with the edge, with a small buffer of space in between the islands and the edge of the map border.

Hi Spyndel,

I got overlapping UVs because i add thickness on my mesh with “Panel Loops”

When i import my mesh in substance painter i got this :

i Tried to turn off “Grp” in export tool but not good too .

Someone have a solution ??
