Well, we absolutely need clipping as the game might run way too slow on low end PCs if we don't use it. So setting clipfactor to a higher value won't be an option for us i guess.
Also, everything runs fine at first. It's only after some time that the whole scene gets clipped away.

As far as i know, only the main camera can change eflag&CLIPPED . Or are there any other ways to change that flag? Maybe we are doing something wrong by accident and turn on clipping for the whole scene because of a bug in our code...?
