I've been working on a map for 2 weeks and the only thing to do in order to release it in beta, is optimization. However, I do not understand Areaportals. I have watched countless tutorials and read countless guides, but all of them show the usage of area portals on very simple maps, made for the tutorial. My map is very big and open and I can only use Areaportals on 1 room. If I seal another room with area portals I get a weird error when I compile the map (something about portalnum > ..). Anyway, it makes me really sad because I was incredibly excited when I imagined playing it with friends and other players, but no matter how much I try to understand how to use Areaportals on my map, I simply can't do it. This is the first time this has happened to me on Hammer and I am even thinking of abandonding the project I've spent so much time and effort on.
