Doe anybody know how to paint a bus, (SD200 series) for example, but without painting over the details in the textures and keeping the window frames etc? Normally you'd expect PSD files to be included with layers or paint over the yellow areas with a new layer set to "Muliply". However the yellow is not a good colour to work with so I need to saturate this but without saturating everything else. Colour replacement works, but not with the colours I need (brown).
Everyone else's repaints seem fine, am I missing something here?
Much appreciate any advice.
