These textures are free for you to use, modify and distribute for any non-commercial project, provided that you give me credit for them and link to this site in some fashion. Commercial licenses for these textures can be purchased on request.
Note to Second Life users: these hi-res textures are now for sale from my Second Life store! This means the downloadable texture packs on this website are no longer permitted for use within Second Life (commercial or otherwise.)
