After I saw all the other rocks I thought nothing further would surprise me. Was I wrong!  ::)
Curious about how they will look with some more terrain.

It's all very well making a cliff on it's own but combining that into a terrain creates a whole bunch of new problems. The underlying terrain alters the shape of the cliff and small fractal displacements end up breaking the cliff texture ...

Smoothing filter to the rescue (it's hiding in "Other shaders").

In many ways this is a step backwards but I'm going to have to overcome these problems at some point so sooner is better than later.
Colour version for fun.

It's a great learning process. Sometimes you just have to go back to basics and work from the ground up :)
Also I love how the chats on this forum inspire and inform.
Those blue nodes have a lot to teach. The Diff-Cliff images are based on multiple layers of Voroni 3D Diff Scalars.

Sometimes you have to read between the lines too! Responses to posts can be a very valuable source of information. Sometimes things explode or warp unlike you are thinking but even then you learn something useful. No shortage of help here for sure, yourself included. :)

Those last shapes show a lot of refinement of your process. They're really looking good!

Great progress. I like to build from scratch every time again. It's like cooking a meal, better start with fresh ingredients than stuffing old fries in a pan  ;)

Some updates.
Really getting into the blue nodes on this although I only know why a little of what I'm doing is working (or not working lol).
Mostly these use Voronoi 3D diff scalar (unmasked and vanilla!) and the cracks use the good old Voronoi 3D diff scalar with Voronoi 3D cell scalar combo.

I'm getting weird artefacts with the strata and outcrops shader so I may have to abandon using that and create an alternative of some kind ...

Some great stuff here Richard...I like the 3rd one best, except for the very long crack running through the entire cliff at the center of the render, kinda distracting the way it looks now.
The others are very good as well though. Each has its own interestingly looking features. The 2nd one has some pretty sweet looking voronoi flattish faces seen in, say, Yosemite.
I don't know what you think, but I think displacement-wise these are 95% finished (it never gets too 100 eh) and shading/texturing will take it next level?

Haha, no it never gets to 100%, but then what would we do?!
Yes the texturing and fine scale displacements are next  in line, although no doubt I'll be revisiting the major displacements soon enough :)
Oh and not to mention I've yet to decide on a good view point, aspect ratio, atmosphere and general environment and all the general vegetation that'll get thrown in at the end because I forgot about it till then!

Have you tried adding some fractal warp to the whole thing - adds lots of interesting and subtle detail.

This is the latest version. I am using FW but I don't want to overdo it. It's a little ott here :)
