That was just a test texture to tweak my UVmap, which I completed last night. As a result I was able to bake my AO texture. Below is a rendering with the AO texture applied.

The mesh is done, the UV unwrap completed and the AO bake texture created. So now I can finally start on the textures for the final look. I have been playing around with the idea of having the model a darker blueish grey, similar to the ties in ROTJ, to further differentiate it from the Lambda shuttle. I'm not sure yet. But I do want to add some color highlights to it like the original game model, but Imperial blue instead of Rebel red.
