, and biotech
Per request of some other folks, I put together some videos of my process.
First, someone asked how I did the "fake" paint-over windows by using Blender's face snapping.
Second, here's a very long (45 minute!) video capture of my entire process of integrating a 2-subdivision and 3-subdivision mesh for the nacelle into a single piece, using the higher-res where necessary. Includes a quick viewport render at the end.
Sadly, I didn't have any on-screen display so none of the hotkeys I'm hitting are obvious, but hopefully the methods are clear.
Definitely watch them in 720p, full-screen, or you'll probably have a hard time seeing stuff.
