Something that's bothered me for a long time is that Valve maps seem to use no texture alignment options, with everything or mostly everything set to x 0 and y 0. How the hell do they do this and still get the texture alignment to look fine? Is it some kind of brush alignment technique planned before? This is something that bothers me because lets say I'm making a room: 128 units wall height. How would you place the ceiling and floor brushes to prevent odd looking textures and optimisation problems. |_| The floor part trims a part of the wall texture at the bottom. Would you use the same ceiling brush as a floor brush in multi-story buildings etc? It's a bit hard to explain but hopefully someone understands what I mean.
