Neither! Since the original had all the fibres sticking out a small amount, I decided to have mine set in a slightly-protruding frame. Completely avoids the need for any cutting, and looks more authentic to the original miniatures too.
The windows make use of a window box shader to fake a room behind. I made 11 different room sets, and close-up using EXRs they look pretty good...:
but from a distance they read terribly badly, so I opted for PNGs instead, and sadly the effect is largely lost:
but honestly, it will do. You don't want to get any closer to the ship than this anyway really.
I spent the last couple of days walking around the ship turning off lots of lights. These Romulans have a habit of leaving them on when they're not at home.
So I'm basically done with modelling now. Just a few things to tidy up before I move on to maps and materials and wrapping it all up.
Lots of greebling has been done. I don't enjoy this kind of thing much, so it's slowed me down more than normal Done with it now though - only the windows left to do now! (and materials, obviously)
