Art Description: 

Seamless shale/slate rock texture from side view, 2048x2048.
The zip file contains a Torque3D terrain material made from it (normal map is not y-inverted).
Game-ready, compressed and integrated version of this material for Torque3D comes also with the Übergame, these are just the source files used for it, in case you need original resolution uncompressed images.

Update: The second file contains a regular material with just diffuse, normal and specular.
