Hi, I'm having a few problems adding a CSG union function to my map editor. Basically, any union between two objects causes gaps, and sometimes overlapping polygons. Below are a few screenshots or the errors marked on them, does anyone know what could be causing it? I thought maybe rounding errors? 
In the second image the square poly is overlapping the red one as you can see from the z-buffer error. I know there isnt much information but maybe someone has a clue? If not does anyone know of any decent tutorials on CSG with BSP trees? I cant find anything other than a small section in the BSP Tree FAQ. Cheers guys. Luke.
