I'm working on the saucer hull plates right now in Campaign Cartographer 2, believe it or not. Then I'll take it into photoshop, do a little blur on it, set the layer to 54% transparent on a grey background, and export it as a JPG.
That's basically how I did the hull plates on top of Operations, though I did it all in photoshop. Since the saucer requires curved sections of hull plate, I had to use something more flexible in terms of curvature, and CC2 was the best thing I had at my fingertips.
I made up a texture for the sensor domes, but I'm not pleased with it at all. The way it wraps the texture around it isn't fun.
If everything keeps going like it has this week, I could be finished with this in a week, perhaps two.
