i realize that there are mutliple light reflecting surfaces on the current cockpit gfx, so getting overly titchy would be complicated. Perhaps just adding a floor and a console or three (simple 1d surfaces in the right place) would make a fighter cockpit feel more large.
Anyway, theres about a million ship bridge concept art pieces out there...but i think simple changes to the current ones would be less glitchy and provide the change us Cap Capn's are seeking.
