I have some similar model parts, so I decided to stack them. In the first photo everything is right – one island is laying perfectly under second.
But in photo 2 – some faces of first island are under second, and some faces are above.
Because of that, I got issues with baking (world space normal map in photo 3).
I used UVpackmaster (vertex position with correct vertices), also asked friend to stack it with Rizom, but problem stays.
Any ideas what can cause this?
