Quote - How did you get so much fine details on the terrain if you don't mind me inquiring?

The terrain is one of Zhann's rock photos on sale here that I tiled through  Seemless application  and then loaded into the pictures/textures source editor in the alpha channel and then cranked up using the edit textures tools using the top icon.Then a bit of applied  bump until I was satisfied.

Doesn't always work but it can make for less render heavy textures..
