Thanks for your answer.
I think you add child layers and change the blend shader and fractal breakup.
You can also add different altitude or slope constraints.
The "thoughts" that went into the image.
The whole image was meant to be a kinda slightly more vegetational advance on Lake Powell and I should have put more ground colour variation in.
http://static.flickr.com/186/428963012_50e87a0bc3.jpgI was learning to get the detail up on the rocks.
The terrain is actually quite elaborate although a bit chaotic.
The eroded effect is not just the erode height-field.
After I put the Strata filter in I tried to soften it up again.. and added several PF displacements down to 10cm..
I would have wanted to add another alpine fractal as a far background as it shows essentially the limitness of the terrain.
There is probably a way to do it with another planet, but maybe also on the same planet, havent figured that out yet.
The water is also a sine wave mixed with an alpine fractal (higher waves) and a powerfractal, inbetween.
I downed the reflectivity on the original water shader.
I added the Huey so I can get scale right. It's about 17.40m
The image is also tonemapped from an EXR as the original was too soft from what you would get photographically on a sunny day in that area.
