Im writing a .map file parser and renderer and i have a question. When i take one of the planes (from each brush) in the map file and create a poly from that plane i will then chop up this poly from the other planes (in that brush). Well when i do this i need to save the back part of the split poly and discard the front. What i want to know is, how do i determine which part of the poly is the back? -SirKnight
