I've been looking at a lot of maps that came with UT2k3, and there seems to be 2 types additive brushes (Blue and Brown additives). Now I noticed this in UT maps as well, and despite my efforts, I haven't gotten any good responses from anyone as to what they are.
Anyone that knows care to share with me

The two types have to deal with solids and semisolds. Semis do not effect the BSP tree so they dont create BSP issues (HOM or Holes). However the semi's dont block the render from showing what is behind it. For example take a big open area and fill it with a nice village. Then build a mountins use semis. The rendering imgae would still have to draw the all of the village even though its behind the moutin and your Frames Per Second would tank. Now if you ues a solid, the rendering engine would not draw anything behind the moutian and life is good.
General rule is to use semis for decorations.
