mm some questions
how much does it matter structurally what the back of your walls look like?
What I mean is, wall A is a simple rectangular solid... wheras wall B has a rectangular face that acts as the wall, but it's backside (caulked exterior) is pyramidal. Does it make any difference in performance? I mean, are the exterior polys completely taken care of by the bsp process? I mean, superficially, the simple solid has 6 faces... all rectangles = 12 tris? and the pyramidal has 5 faces (1 rectangle), = 6 tris? I seek enlightenment, oh mappy ones.
