Hi, I'm working on a skin for the Pagani Huayra and I'd like to paint the rims in the same gold color used on the zonda. I changed the rim base color and used rim_map to get rid of the chrome-effect, but the closest I get is shown in the images below. Regardless its color, the rim_map always results in a very dark layer on top of the base color. Changing rim-detail doesn't seem to affect anything. Is there a proper way to paint these rims without changing their material? Thanks!
