I have a problem with my next map, New York. It's a very large, open map with a 360 panorama view of the entire map from the top of a skyscraper. Basically, it's a "technical" mapper's nightmare. I'm hoping to mirror the part present now to make the map twice as large! But unfortunately, BSP does not seem to be advanced enough to handle such a large, complex map.
Anyway, my problem is that it says, "leaked" when I can't see any leak. Can someone please help me? I've attached my .map file.
P.S. Can someone also help me use "hint" brushes effectively? I'm confused about them.
