Well, here we go. First I used just the normal Hammer compiler, just to see if it worked. Apparently, not though, as it crashed fairly quickly. So I went along an alternate route, I tried manually compiling. I first tried to run my VMF through VBSP but unfortunately that crashed as well (see a pattern?). SO I compiled the bare BSP in hammer and then ran that BSP through VVIS, which performed like a charm. Then I moved onto VRAD, which after complaining that none of my props could be found crashed fairly quickly. So, can anyone think of any ideas? All along my map making process, I have had horrible issues with simply compiling my map. I have only managed to create one working version, and then I found many bugs and other various issues which I had to fix.
