And before anybody asks, yes you can use these textures for non-commercial, commercial, game, etc. They just ask to give credit with a link back to their site.
Thought I would share this with everyone here...If you are a "Free User" (someone who has not purchased an appropriate Genetica license and instead uses free or demo software):
a. You may use the preset and pack textures in both commercial and noncommercial projects such as games, movies, publications, and artwork. You will not owe us any fee for this activity.
b. You may modify our textures to whatever extent you see fit. You will not owe us any fee for this activity.
c. You may redistribute our textures, but must clearly and visibly link to our website as the source of the textures. If you do not wish to credit our website, then you may instead become a Paying Customer by purchasing a license for Genetica
I have already started using some of them. You can look at OuterNet's page under member games to the last post I made. The whole landscape was with these textures. About 4 in total!
