I've gotten a lot of requests from people asking how I did the textures for this ship, so I decided to post a sampling of the diffuse maps. Most of these are reduced by anywhere from 50-75% from the ones used on the actual model.
B/C Deck Command Module:
Nacelle Inner Body Grill - Diffuse, Bump and Opacity Maps:
The specular maps are, for the most part, just darkened and higher-contrast versions of the diffuse maps. What really sells the textures is the material setup in Mental Ray, which I unfortunately don't have time to go into right now, but maybe some time down the road.
