"You can't always get what you want" - Mick Jagger
Stuff like this is fun to do but in the end it's not going to work without major revision, most of the map is visible to the rest of the map (to the engine anyway). This is kinda what ub rooftop was like when uni 1st handed it to me, a big open 3500+ rspeeds space. Don't take it the wrong way though, I did this too (so did Delirium when I showed him the basics) it's just part of being a mapper, the sudden sad realization that you cannot do just anything you like but must work within the limitations of the engine.
