<p>GZDoom Builder is a Doom Builder 2 fork, which aims to incorporate as many GZDoom features as possible. Currently it's the only map editor for Doom and games based on Doom engine, which supports 3d-models, dynamic lights and colored fog.
<p>This is the Reference Manual for <strong>GZDoom Builder</strong>. You can use this manual to look up how the specific GZDoom Builder features work and what the specific modes and actions do.</p>
<p>This manual is not a beginners tutorial that teaches you how to make maps. To learn the mechanics of how to make maps read <ahref="http://www.doombuilder.com/files/doombuilder1guide.pdf"><b>Doom Builder: An Illustrated Guide </b>(http://www.doombuilder.com/files/doombuilder1guide.pdf)</a>.</p>
