Ok, I need to know... Is there any way to delete polys in OpenGL? Also What kind of collision system does the Unreal Engine use? I was wondering ''cause Deus Ex uses it, and Deus Ex is gravy, and I wish I could do collision that good. What I mean is, how could they possibly put collision boxes around every section of terrain and every model and all, especially if the terrain was rounded. En taro Adun!

Uh, come again capin? I''m not readin'' you clearly. Do you mean have like a loop that draws the polys if a var is true, and not if it is false?

You dont use bounding boxes for collision with static geometry
