This is my first post here so I guess I should say hi The tf2maps.net tutorials and forums in general have helped me out tremendously in making my first map. I'm pretty comfortable with the layout and general flow of my map (it's a fairly simple CTF, something good for me to start with). Right now, I'm at the stage where I'm adding details and lighting so everything doesn't look so awful. I've seen in numerous places that I want the majority of my brushes to be func_detail, especially main walls, floors, and ceilings. Is this correct? Also, I was under the impression that every brush created was a func_detail by default, so I really want to go in the opposite direction. That is, make essential view-blocking brushes (like pillars in the middle of the room) part of the "world", or a "world brush", or whatever the appropriate terminology is. Would this also be correct thinking?
