Hola. I was wondering if there was anyway to have hammer not think a sealed off area is a place a player can get to. I have a decent portion of water in my map that you can't go to, but has to be there as a skybox would block off other parts of the map. This would take time out of compiling and weaken optimization right? Thus I was wondering if a hint brush would work here, and how would I place it if so. All over the area? or just as a wall? If not, what could work? Thanks in advanced. Sorry if this has been asked before, kind of a hard question to search for.
