I''ve read some in the collision-detection tutorial at NeHe, but as far as I understood, its only for sphere''s, cyllinder''s and planes. But how do the big guys do it? ie maps made in worldcraft. Maps tend to be more complex then spheres and cyllinders. To note is that Im working on my very first 3d-engine, wich currently load maps made partly in Lightwave 3d.

see: Generic Collision Detection for Games Using Ellipsoids

It demonstrates a way to have per polygon collision detection using ellipsoids. I don't think it could be more advanced/precise and it certainly is good enough for a FPS.
