Making a metal floor I have a little problem. Attached you can see a metalplate which has knops on the surface.
Every knop has a dark border around the top. And this is the problem. In the Normal map it will show a little gap instead
of staying high. I have tried some different ways to avoid it. But nothing worked. I have also tried to work with different
technics like displacement or bump maps. And also here I was not successfull. Maybe one of you has an idea.
