Hello I've been doing texture work for a while now, I decided to jump on substance painter from now, and learning little by little, but I'm running on this problem. I want to make a bump map for bodies (ebody reborn on this example) I'd like to make scales, but I have this problem when I want to add scales to the arms, since one of them is mirrored, the scales are inverted (appear sunken), the same happens with the legs sometimes, are there special parameters or configuration for the material mode on substance painter? or is there something else I could do? Any help would be greatly appreciated First picture is what it looks like on substance painter, second picture is showing the issue with the inverted arms
