That's because they're bump maps. With the angle to the camera, the illusion us being lost with the windows on the edge of the saucer. I believe the concensus was that AO and displacement maps didn't play well together, at least not with v13t. Maybe I'll play with it more when I upgrade to 15, but for now I'm happy with Eric's new maps. I have to move on to rebuilding the nacelles. I have nifty plans for them.....nifty, I say!
