The preprocessor is done.
A couple of slight annoyances: txqbsp isn't, in fact, compatible even with the doors as-is. I think I had a super coincidence with the one time that it worked, I might have had the actual center @ 0,0,0 which is the only spot on the map that it may actually work with txqbsp.
And hmap2 doesn't like the texture alignments in Worldcraft 3.x (Valve 220 format) and some surfaces the textures aren't the same as in the editor. It also somehow crashes the editor upon compile (but I can work around that

Still I'd like to find out why ...).
Haven't played around with the Half-Life compile tools yet, which already support all of this stuff anyway. I don't have whatever version of Visual Studio that is requierd to compile Zoner Tool's ... but since Zoner Tool's appears to support compiling via gcc and I have Cygwin all figured out now (I want to change some defaults and holy texture names and the hull size, of course

)
