Thanks to all the help, i finally got my q3 Beziers running and now my thing looks just like q3.... But clipping for beziers isnt in the leaves and nodes or the planes, i assume i have to generate my own planes and all.... Is there anyone who has done this before who can help me with it? Basically i just want to implement the collision planes into the current q3 system but if its not possible then i guess not~!
