I am working on some map and during my building and adding and so on and so forth i had this ideea what if it will take couple of hours or days to compile my map. And now i'm thinking on how can i reduce the compiling time? And, has the lighting anything to do with compiling time, and also sky box? Does the vis calculate everything trough skybox, if i make the sky box smaller or a different shape than a box, to shrink the unusable space betwen brushes and the margins of skybox then also vis will have less calculations to do?
And the other thing is. i have seen that texture NODRAW and i am using it on sides of brushes that will not be visible to the player is that going to reduce the memory load in an ingame action or no?
