I've recently gto back in to Ultimate Doom and Doom 2 in a big way. Back in mid-90s, I had a go at making some basic maps with a free editor called DoomCAD which came bundled on a "PC Attack!" magazine cover disc.
Anyway, so I found http://www.doombuilder.com
and downloaded it (excellent editor btw). Is there much id Tech 1 mapping knowledge here? If not, can anyone recommend a good site where I could post up questions and problems I encounter? I had a look here and it looks like sub-forums are just for id Tech 4 and 5.
Anyway, so far so good. Tutorials on Doombuilder's website are getting me going and it's fairly basic after mapping a little using GTK Radiant (for id Tech 3) and Hammer (for a HL2 mod), and my previous hazy experience with DoomCAD must be helping. Also, again, the tool itself is very user friendly so that helps progress too.
