Leaving the mountain road again, inspired by René's work, I had a go at squarish rocks again. Two renders; RT and PT newest build (robust sampling). The main difference is in the foliage of course, but (in both) I had the opacity down to 0.6 or so, which is very clear in RT mode. No postwork.
I like the foliage of the PT version more.
But both anyway gigantic!
Great... I like PT :)
Interesting how much the shading in the cliff (on the left) varies with PT too. You see stripes in the texture where you didn't before. Probably due to Defer All, which is used for PT. You could try enabling it for the non-PT render to see if that's what's causing the terrain shading difference.

I may try that later on, but first another iteration. No yet satisfied, though, some nasties around.
Updated. Path Traced. Took 2hrs with mpd 0.6 and AA6, soft shadows 6 samples.
Ah - your latest is by far your best. Especially with the color variation and narrow cracks.
Great! And once again the path tracer makes it look much deeper.
Absolutely agree!
I love especially the look of the trees foliage now very much!
Note that with Path Tracing (or just Defer All) you can use much fewer Soft Shadow samples and save render time. Often 1 is enough.

Thanks Oshyan. I remember it's been mentioned before, but I have to get those changed parameters into my mindset.
latest is great
Another setup, rendered in PT. Generic v3 low clouds (cloud quality 0.3) mpd 0.6, AA6, but they are grainier than expected. It's a bit too cloudy, btw. I wanted sun in front.
The wolf rock is a cube. The big rubble flows are masked by flow map from Daniil's erosion shader, which was only used for masking.
Rock face looks darn good
Still struggling along.... trying to get a decent area where rock broke loose and tumbled down. I have to use negative rocks to get the holes in, I guess.
Thats such a sweet detail - that sunbather on the stone :)

...trying to get a decent area where rock broke loose and tumbled down...
Curious how it will look.
I would try (at least with some smaller) rock populations on top of this too just to see if it would help or not.
Still struggling... PT render, took 4+hours. Negative rocks didn't work, so I opted for some voronoi indentations.
You want probably a one surface solution but a second planet or plane like method might be easier?
Are you using Robust Adaptive Sampling, non-customised? Some of the shadows look too dark to me, which can happen with the legacy sampler. Robust with default settings should render faster too.
No I didn't, as I found the clouds getting grainy in earlier versions. Even when setting cloud detail from 0.3.. to 1. Thought Robust rendered much faster indeed. But the dark shadows is likely due to some post enhancing in PS.
This one (still with issues) is RT rendered again.
I don't want to be pedantic, but in my experience the best and easiest way to make those indentations is with the painted shader, at least if there are not too many. Once you are satisfied with the rock texture you can paint in places where it is most logical, like in the cracks that are already there.
Maybe you will need to feed the fake stones through a transform shader– world space, and limit it with slope– terrain normal. Sometimes that gives better results.
Thanks René. Well, that was one of the issues I meant in the latter render, forgot to use a max slope. It looks pretty weird indeed. And actually I prefer using a procedural base to get the gullies in, mainly for changes of terrain/rock seeds, and corresponding 'easy' stonefalls. But you're right, with small numbers and an established terrain a painted shader would be the way.
And it doesn't sound pedantic at all, any input from you is greatly appreciated!
Rocks will not lay on slopes above 45 degrees, any higher and they will roll down. One or two may get caught on ledges.
Beautiful and great work !
Now with max slopes and some other adjustments. I'm not satisfied with the rockfalls though.
A pity that the rockfall is missing :'( I liked the one with the slightly brighter rochs in "SquareRock_v9_29-03-19 test 13.jpg" very much.
But anyway great cliffs!
