I'm working on a custom map for counter-strike source and there is a really wierd graphical error.
according to the compile log there is no leaks.
Here's a copy of the map source.
I was able to get it to go away by removing all of the rafters but I would like to avoid that if possible.
Also note I didn't properly splice the corners so they have less faces but it had this problem even on my previous attempt when they were done correctly.

Found a solution, which was to move back the rafters 1unit from the outside wall. Normally I would try and avoid that but its barely noticeable up there.
I'll post the completed map in my sig when its done someday.
