heres the problem

Too many unique verts, max = 65536 (map has too much brush geometry

Probably has to do with the fact you decompiled rockford, I wouldn’t recommend trying to recompile a decompiled map, especially one so large, and without the authors original copy. You’re going to need to delete some brushes.

its the one from his thread that he posted. http://forum.facepunch.com/showthread.php?t=1457326

ah yeah… well even with the source you can’t just weasel out of the facts. You just have way too many vertices. Either downsize them and have it compile. Or, you can optimize it by using entities and models. Or, you can do none of those and just work on something else.
