Hey, Matt, I think I'm on to something! Found a good (old, but good) Gimp tutorial re FSX bump maps and it worked! I was able to create new bump maps for the model in question by using Gimp's bump map plugins and the tutorial. It is fairly straight forward, just have to make certain to follow the directions exactly the same way every time. Now just have to fine tune the maps to get the outcome looking the way I want.
Thanks very much, Amigo, for your offer of assistance and your willingness to help a painter(s) in distress!
