I have been working on a map for quite some time now called gm_paradox (http://www.facepunch.com/showthread.php?t=911786). Until recently, I have been compiling only the main section using cordon tools. The map is pretty much finished and ready for a beta release, but I cannot for the life of me figure out why it crashes hl2.exe when I load the map in gmod. It compiles fine when I leave it overnight (I run vrad on fast, everything else on normal), and I check the log for errors with interloper’s compile checker tool when it finishes. I’m using textures and models that aren’t supported in the episode 2 editor but are from other source games like CSS, but from what I understand that’s allowed so long as gmod supports them. The map is very well optimized and func_detail is used on anything complex (including the circular main area, which is cut into a diamond out of the circle, with the outer half-circles left over tied to func_details). The map includes a very large water section, several floating islands (which are identical at the moment), a fancy elevator up a glass tube into a teleporter room, and several rooms. The spawn points are areaportaled with no windows. I was hoping you guys could provide me with some possible reasons why hl2.exe might be crashing on loading this map. I really want to get this map beta released so I can start adding community requested features. This is really the only road block stopping me from doing so.
