Alright. So I tried making the ceiling on my map func_seethrough but when I compiled, it came up with a leak. I went back and turned it into a func_wall and the leak dissapeared so its not anywhere else in the map. What are you supposed to do to make it so you can make it without causing a leak. Thanks .

Unless you have a skybox then it registers as a leak in the level. When you get a skybox put the skybox texture against the window.

You do not have to make the ceilings of your map func_seethroughs, because NS automatically looks throught ceilings. As you (should) know, entities do not block vis, wich means turning the ceilings into entities results in a leak. You use func_seethroughs only for things that you can see in commander mode but don't want to see.

okay thanks
