IMHO it would be Asking WAY too much to apply that level of detail to a Uboat interior.
Its fine to model that L.O.D for a dozen small & confined Airplane cockpits, but to do it for 3+ HUGE fully explorable Submarines?
Its about 1000 times more work. theres just no way
Im very happy with what we have so far in SHV - besides, other areas of the sim demand more attention anyway.
(And you can only stare at a bunch of pretty valves & dials for so long....)
