I'm wondering how to create a car shader similar to the ones in these pictures. These are renders from Colorsponge using Vray. Whenever I try to create car paint, it often turns out mediocre. In my shader, I include normal flake maps, bump details for the coating layer, and some roughness details. I believe the issue might be related to the scale of the flake normals. However, when I scale them down, they just make the paint look noisy and rough. Could anyone recommend any tutorials on this topic?
Thanks!
