The aztech texture set was created by Tom Perryman (phantazm11) and may be used for non-commercial use only as long as you include my name and email address in a readme file included with the map they are used in.

If you use any of these textures, please send me an email at: firstname.lastname@example.org
This texture set will be offered soon as a stand alone release under the creative
