Doing a full compile of my map takes over an hour I guess that's way too long, even for my slightly large map with many lights. Optimizations I made were making lots of non-structural brushes func_detail and applying nodraw to many faces that a player will never get to see. I need to add some cubemaps and rebuild them, so I have to do a new full compile. Sucks to wait an hour again, plus now I wonder if my map isn't too poorly optimized to perform well for users. Correct me if I'm wrong but isn't the last thing I can do to optimize is to build areaportals? Will this bring my compile time or is it only profitable for players? If it does help, can anyone help me understand how to use them, because no matter how many tutorials I read on them, I still don't understand the principle.
