Here's a ship I meshed out today. No name so far, though I've tried a few different variations on ideas I've seen in many other ships, including a triangular secondary hull, as well having the nacelle pylons extend out from the very bottom of the ship. It's tough to get them to integrate smoothly from there.
As you can see in the pictures, the ship will also have a separable saucer for MVAM. MVAM seems to me vastly underused, so I figured I'd give a go to it as it's not that hard ot mesh out the ship that way.
I've also tried a few different styling cues for the engines. Still plenty of work to do on the whole thing, mind you, such as impulse engines, torpedo launchers, etc. I'd like to ramp up the modeled details on this ship a bit, given some time.
So far 8100 polygons with zero errors, and I haven't gone through to reduce where I can yet. I'm going to shoot for very high detail with a ceiling of 15k for polys.
