Looks good.

This was the mask I was thinking of.

Last picture is very nice!!

@ Ben; I'm afraid it won't work that way as you need smaller displacements, not just a hardening or softening of the first fractal. In the same surface layer it is easier to just add a vector displaced small fractal with min height and min slope.

Very good. I like the results with the added low fog in the distance and the large, reddish rock outcrop and the change you've made with the clouds. I would expect you will back up the camera and show more of the foreground as you did with the first image?

Like the latest version.
I wonder,if the problem might be caused by the stretching of the noise.
What do you think is the reason?

[bigben]

I was only suggesting that as a replacement to the altitude restriction. It automatic starts at the range of your larger displacement and can. Be easily tweaked with the colour adjust node without having to determine the the actual elevation.

@ Ben; I don't understand that, but it's early morning, so I'm not fully awake yet.
@ Jochen; I don't have a clue. It can't be the stretching, I suppose, as it's still restricted to a certain height.  I may find out, although it's not really important.

EDIT: I know what it is (quite logical actually); the downward displacement is done áfter the distribution shader limits the height of the small fractal, so it doesn't yet have a clue about what height it's referring to. No matter if you use final position, it just doesn't 'know' yet before it starts displacing.

I did have another play and came up with an even simpler solution, without the warp shader. Turns out it doesn't accept heights somehow

the last image (on the previous page) is very good and especially the island which is simply superb (what kind of tree did you use for it).

Agreed,it's not really important,but interesting.
If you are right then that might be the explanation for the effect I noticed
and that made me think of the stretching as being the possible culprit,too.
Don't have that much time for TG at the moment,so I just had a really quick
look.The aforementioned effect is that the displaced fine ripples start to show
with a min altitude of minus 2.At zero or minus 1 nothing shows (as expected),
but then it starts to show and its running all the way down to the ground,which
was surprising to me.That made me wonder,maybe a lack of pre-compute terrain
experience on my side,though.
Anyway,curious to take a look at the latest file tonight.
