K, the aztec patterns are mostly just a tileable texture that I placed as the background of my textures when I drew them. For the saucer though, it's a little different, since you need a rounded pattern. It took a little experimenting, but I actually did that in Max itself, and it was rather easy, with some experimentation.
The trick is that I didn't draw the aztec patterns on the saucer, I rendered them.
To get the pattern right, I took all the saucer areas with rounded panel patterns, applied my aztec tile texture, and applied a cylindrical texture map to those areas. It won't work if the saucer is completely flat, since it'll just stretch the texture all over the flat faces... but with the correct UV scaling and tiling settings on the map (very high tiling numbers I think, with pretty low scaling), you'll get the aztec patterns wrapped around the surface of the saucer very nicely. It does take a lot of trial and error, but it's much faster then drawing them manually.
The easiest way to do it might be to just make an oval-shaped cone that approximates the shape of the saucer, give it the cylinder map and texture, and use that in the next step. Just to be safe, I'd make a copy of the model just for experimenting this way, since you might need to alter the saucer to make it work right (I think I did, which is why I think the bottom surface of the saucer is not entirely flat in some places).
After you get the panels looking good, set the tiled texture illumination to 100% to remove shadows, set your render background to black (or some other easy to filter color), and render a top/bottom view of the saucer (or imitation saucer). Make sure the image resolution is decent for the size texture you're making, then just copy/paste the render into your texture as the background for the saucer details.
I imagine you could also do the same within the model, modeling a few panels, and then using some feature of Max to tile them around the saucer, but I really don't know much about how to do that (I may have to try it someday though, would look awesome to have the aztec panels modeled in
).
