This was initially a evaluation of sand drifts but while playing around with my mix controller... well... It went crazy. However it is a very unique and intriguing look indeed so I immediately had to save the nodes and share them with you all.
Not sure of it's applications. It almost looks like I was re-inventing the "fake stones shader" or something. Maybe you all can come up with something cool with it.
The scales on this terrain are very small, so you must zoom in at your terrain. To get more "bumpy" terrain, adjust both PF master scales to a smaller number like 0.2
Cheers!
Ps. In retrospect with a friend; I apologize if the surface is mooning you repetitively....
