yeah scorp, i've been reading up on the detail deal. still not clear on exactly what you would detail (every tut says "whatever you don't want to be seen") but i think it means anything not dealing with a wall, floor, ceiling, ground, sky. most of my map is exterior (lot of climbing up and down skyscrapers to make up for lack of interior play).
the map's kinda big it's dims are x=6008 y=5688 z=3712 but nothing outrageous (no more than CN
aylight in width and length)
i'll proably try and get with you on msn messenger later this week to go over a couple mapping questions i have.
