Bump mapping

[Aero]

When repainting textures I notioce that I seem to erase some of the bump mapping used to give the vehicles a realistic apperence. Is there away to change the color with out making the vehicle look like a caretoon? If so let me know.

Use the magic wand or magnetic lasso to select the area, then go to image-adjust-hue and saturation.
