So I'm trying to use an overlay mix shader to map a skin onto a replica of a car from the video game BeamNG.drive. It doesn't look right, still. As you can see in the comparison, the camo is covering up the grille, which is an effect I don't want. Is there a way to fix this? Below is a download link for the blend and textures, too.
