Okay, when your thread devolves into discussions of MVAM and UFOs, it's definitely time to post some WIPs.
Not shown here is a fairly massive amount of vertex editing to create those scribed panel lines after the boolean operation was used to cut their basic shape into the hull. I was going to create some WIPs of that process but I got so absorbed in actually doing it that I forgot.
Believe it or not, this whole model is still well under 300,000 polys. In fact, it's still only about half the size of my Polaris
model. But, of course, I haven't started adding windows yet.
