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 √úbergame, 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.
