It's looking good, Thomas! It reminds me of the mountains we have around here,
but ours are grey with many round stones, and little more rounded at the peaks.
The high country. Beautiful, yet treacherous.

Are you using the free version of World Machine which has a 512x512 height field
resolution limit? If so, I know of a way to get even higher resolution maps into
POV, but WM is not involved. You can use the free version of Terragen to make
your HF, import it into TerraBrush, and then export the HF to a 16-bit bitmap
format. Terragen's erosion functions are terribly slow, but it's the best work
flow I could find for Windows.

Just thought I would share that since I spent a long time searching for a
solution, and the info is useful :)

Thank you indeed Sam! This is useful info. I do indeed use the free version 
of WM. What I often do (not here though) is to load the HF into GeoControl 
(or Leveller) and increase the resolution and maybe add some features before 
exporting to POV. I confess that I forgot about Terrabrush which I used in 
the past along with others. Also Terragen has been somewhat neglected by me 
these last couple of years. I like to have several and different 
possibilities for approaching a goal.

Wow, really nice so far Thomas, looks great overall!

Here's an idea for some foreground detail: I often use some simple height_field
ledges/rocks scaled quite small and traced down to the surface with
Reorient_Trans, randomly scattered all atop/inside/through one another for some
detail. Or maybe simple isosurface rocks done in the same way, randomly scaled &
rotated.

I'm really looking forward to seeing your progress on this one.

Now I'm off to Amazon to order that book, I need a good read for the holidays,
thanks :)

This is interesting I believe, although still far from perfect. What I did 
here is:

- introduce a spherical pattern to make the normal in the rock texture 
gradually disappear;
- add trees to the background valley with a treeline somewhere in the snow;
- add rocks to the surface and make them scale down with distance.

Thank you Robert!

Good idea abou those ledges. As you will see in the second wip I just 
uploaded, I used a mesh rock (need to use 1 or 2 more for differentiation) 
with the added nice touch that they are gradually scaling down with 
distance. This way I can play with the illusion of distance. VDist(V1,V2) 
and little simple calculation did the trick for me.

The foreground needs some *real* snow now.

I hope you like the book. Imo, it is the best in the Mythago Wood Series of 
which it is the second. They can be read separately though without much 
problems.

It's looking even better now. The rocks might need more variation in their
sizes, perhaps with some squishing and stretching. Are they height_fields?

Occasionally I think about new ways to populate a landscape with rocks. One of
these days I'll have to try modeling a set of them in Blender, decimating the
meshes to reduce the poly count. Now that I know an object pattern can be
created from a mesh, I'll have to try giving the rocks a proximity pattern...

Thank you Sam. I am on the right track I believe. Still work to do though. I 
only used one simple mesh rock here, but I shall increase that number to 
three to get more variations that way, but as you said, more differential 
scaling is also in order here.

Object patterns... hmm. I shall have to think about that too...

Neat.
Ok, it is unfair in an unknown region, but it could be interesting 
having a path, perhaps signed with red or orange paint on the stones.
And what about an animal (a bird or an ibex)?

No! No! No path here! We are in really wild territory where few humans have 
trode  :)  Consider yourself as a scout...

Please be patient. Animal(s) will certainly appear in a later stage, when I 
am doneand satisfied with the landscape.

Looks like lammergeier country to me. I bet you can't find one of *those* on
Daz3d!
