I added my first *real* :p tutorial today. It teaches you how to add specular mapping to textures with the id tech 3 engine. Check it out!
You heard it here folks! I've decided to allow the community to gain access to the .map files for two of my maps. This means you can feel free to use them, build new maps upon them and tweak them to your content, etc. Just be sure to give credit to me and that your new creations are released under the same license. Also, you must still contact me for permission to use them in commercial games. Both are released under the Creative Commons NonCommercial-ShareAlike license.
You may be wondering why I didn't release Training Day. Well, that map uses Quake Live textures, and I'm afraid I might get into some legal issues with id distributing such a map's source file. So that will be left alone. Any future (non-commercial) creations from me, however, will be licensed like this.
