In Unity:
So i have weird 3D model normal texture problem (most likely i just have skill issue) but any way
in substance painter its looks fine, but in Unity its broken like in screenshot
and im pretty sure that i used same model with same UV map like in substance
By the way this is how it looks in Substance:
I can’t imagine it being anything but a UV issue.
What happens when you put some kind of UV testing texture on it?
The issue was that i was importing FBX model straight to Unity without triangulation, when i export model from Substance Painter with triangulation it fixes issue
