Which bloody compile is the 'nolight' compile?!?!
Amazingly the ones that don't have the word light in them!
(single) BSP -meta
(single) -vis
(single test) -vis -fast
To see how your map looks, use (single) BSP -meta. To see how the final FPS will most likely come out (without having to compile light), do a (single) BSP -meta followed by a (single) -vis.
The (single) -vis one is the VIS stage...if you're making a big/complex map, search on here for max_map_visibility so you don't go posting about it if you get it :p
