I have not yet started on spacecraft, but if anyone is interested in
exchanging Lightwave objects, I am begining to amass a good sized library.

No problem. Create a brush in your favorite paint program that is made
up of little patches of similar color. If they are to be very regular
you can make them one pixel each. Otherwise, larger less regular patches
would be appropriate, maybe some overlapping. Then map this bush to your
spacecraft surface with the appropriate scaling. You may have to break
your object up into separate surfaces to get optimal results and be careful
of which axis you specify for mapping. You could then add other details
like hatches, planetary ID's, etc. by placing a detail polygon in the
appropriate place and using a surface color map with a brush of a Federation
logo (for example) along with a transparency map with the same brush
to allow the surface below to show through wherever the logo isn't.
