OK, I've been away for an awfully long time. Much busier "real life" stuff to tend to. I wanted to build a new starship, something of a generally familiar design, but not seen before. I consider this a bridge between the refit Constitution class and the Sovereign class. It's just a bit taller than the Constitution class, but much longer. I built it principally with subpatches.
I figured out the issue with the UV maps and got rid of that weirdness. Added some lights. Rebuilt the nacelles, including redesigning how they're lit.
