Im making a paint for a C-40A which is listed below, my question is this.. Is there a way to seperate the wing textures to have a seperate texture for the left than the right? As many know, military paints require stars and bars on the left wing, with unit designation and tail number on the right for topside and bottom side stars and bars on the right and branch of service on the left. Can this be accomplished in any way? I only see one genaric wing dds.
