I can't see what Carl's talking about because he can't seem to post a useful link.
Thrusters are things on the tail end of moving ships. Unless you're moving in really close and doing your best to get a dodgy angle, you simply won't get a dodgy angle. Furthermore, if you handle the layout of the polys properly, even a dodgy angle doesn't look bad.
I'd rather see thrusters done in the Iwar2 manner, but A) nobody but me likes thrusters that cut off, and B) you'd have to rework the entire POF structure. And god knows, we don't dare change the way the game works.
