Hi there! My first post =) I've waited quite some time with posting because I've found all my answers in searches and I haven't completed anything yet. I've been working on a payload map for quite some time and I've come quite far. I'll give you a small teaser below. I've paid little or no attention to optimizing (except when it comes to the obvious; not too much complexity or too "big" areas). I waited because I thought it was smarter to wait until I knew that the map won't change (not so much anyway). So here I am, sitting in hammer and wanting to place some hint brushes. I've read the VDC tutorial, the page explaining visleafs and a couple of threads here. I haven't been able to fully understand how exactly to use 'em! Someone claimed that areaportals are better (?), some have said Valves proposed method for hintbrushes is a waste of time, VDC-guide claimed otherwise of course and some suggest the brushes should be placed horizontally and over large areas. I just don't know what to do =) Also, I have a part where a skyboxbrush is viewable from two sides. How do I make it so that the other side doesn't "show through"?
