BTW, something that people here should know (tho imo blitz's bsp loader is too limited to be useful (unless someone knows a way to access the textures, etc. that I don't))
quake 3 source was released under GPL including a recent update with the tools source also GPL and GTKRadiant was recently released under GPL.

Well, I compiled q3dm7.map(sample in Q3 folder) and it compiled and it loaded, only problem was I have no idea what loaded since there was nothing there when the program ran. Strange. No doubt I didn't set it up right or something...who knows.
