Hello, I baked the normals from a high poly to a low poly and am getting these lines (artifacts) where ever my seams were. Does anyone know how to fix this?
I played with the margins increasing it to 8 and it reduced those lines a lot. Maybe that is all I can do?
Another thing that would really help is changing the background colour to be 128, 128, 255/#8080ff as black is the worst possible colour that you could possibly have for the background of a normal map
As for the padding, I never use less than 16px (you can’t have too much ;)), but ideally you would every pixel in the background to be padding so that no background colour is visible as this would guarantee no errors when mipped. I know some people don’t like the way that this looks on the texture though, so 16px should be a minimum.
Padding might have been argued upon but blue (0.5, 0.5, 1.0) is now the default clear color for tangent space normal maps. Possibly the last fix before release…phew!
