Fake-stone Help

[swissAdA]

Hi folks, can someone tell me or help. I am currently using the Fakestone-shader in conjunction with the Power fractal shader as the surface of the stones. Now, unfortunately, I understand the individual functions are not quite. What I really want to know is:

Example: Stone scale = is the percentage or metric?
and I would like to know the following properties.

Fake stone shader:
- Stone scale
- Stone density
- Stone tallness

Power fractal shader:
- Feature-scale
- Lead-in scale
- Small Scale
- Noise Octaves

I hope someone of you can help me. or someone has a good tutorial for me?
Ever many thanks for your help.

It's pretty much a tech article, but it should give you all the answers you need about the power fractal...

As for the fake stones:
Scale = size in m
Density = coverage of thee stones in a given area in %/100
Tallness= vertical size of the fake stones in %/100 of the "scale" specified in the other node tab.

Cheers,
Frank

Regarding Frank's description of density and tallness; That is, where a tallness/density value of '1' = 100%.
I think as you go past '1' you are, in effect, stretching the dimensions of the stone in tallness values, and overlapping the density.
A density of '1' is pretty much complete coverage(you'll find it isn't total ground coverage, though) and,
a tallness of '1' is a stone of roughly the same measurements on each axis, like it would fit inside a sphere with its extremities touching the inside(approximately).
The default 0.5 tallness is pretty natural for a stone on the ground in real life, half is most probably buried underground.

Another more descriptive explanation with images was here somewhere about two years ago and it was very clear about the fake stone populations in a very distinct manner.  Maybe I can find it.

you mean this? http://www.martin-brunker.de/tutorials/ger_tutorial3.htm

it's german, though, but the many single images have the settings used next to them, so it's probably still useful even for non german speakers.

and google said, let it be english (well... kinda... easier to read then german to us english readers )

Hallo Frank,

schön, dass Du Dir die Mühe machst, nun auch etwas Licht ins neue TG 2 zu werfen, da planetside es trotz immer und immer weiterer Verzögerung nicht schaffte, eine download-PDF zum Launch bzw. sogar bis jetzt zur Verfügung zu stellen (die Erklärung, ein defektes Notebook sei Schuld, kommt nur peinlich bei mir an). Bin mal gespannt, wann das 'Handbuch' nun kommt... Deine website gibt jetzt zumindest in zweierlei Hinsicht etwas Lesestoff und Grund dazu, das neue TG 2 spielend zu erlernen. Weiter so! Ich komme mit der deutschen Sprache sehr gut klar, spreche ich sie doch nun fast schon 50 Jahre lang.

When I use the fake stone shader, sometimes I will take the output from the 'stone' surface layer, and plug it into the fake stone shaders input. Since I usually apply displacement and color data in this layer, the fake stone shaders 'look' right. Also, it's easy to make many fake stone scale sizes, since the displacement/color comes from the output of the 'stone' surface layer.
I also use small to large fake stones for rocky hillsides. Start with the smallest fake stones. The larger ones usually cover the smaller ones, and the smaller stones add detail to the larger stones.
