Hi,

I was wondering how to create weavy strata. I got an idea reading a tutorial about functions(http://forums.planetside.co.uk/index.php?topic=1167). here is the first result.
The image uses mainly sin an cosine functions + some fractal shaders to create random effects.

Maybe I'll try to improve lighting and the usage of fake stone shader.

For color... well I am almost totally color blind so keep cool.  ;)

### NEW EDIT ###

A new version is available here (cracked rocks, new sky and some texture in the foreground):

I used the code from "Cracked_Rocks_010807b.tgc" to modify the boulders. by the way I have got really strange results:

if I link directly the output of Cracked_Rocks to the Surface Shader input of a Fake stone shader, it works very well in a minimal scene; but in my case, it affects the whole scene textures, although the fake stone is a children layer of a very limited surface layer.

To make it works, I had to remove the displacement layer of the Cracked_Rocks, and add one between the Fake stone shader and the surface layer which support it.

### NEW EDIT ###

last version here. I had to fight a lot to have a good material using xfrog plant, is there a tutorial that help?

I like grassy hills and the beautiful sky.  Need more texture in your foreground rocks, eh?

Interesting results with the strata.

some changes added in original post.

This reminds me only in part of Omaha Beach in Northern France.  The long beach would need to be sandy, though, and the hills are less pattern-wise and very bushy.  Those guys had to work their butts off to get up those hills even without someone picking them off from the tops.  Anyway...it's what I thought of when I saw this.

I have post the last version of this trial. (see first message)

It is almost 100% functions + fake stones and 1 XFROG plant, I will now try to create something that look more natural.
