Simulating sand with rocks challenge

Hiii

I was trying and searching a lot to simulating sand with rocks surface

something like this pic here

http://www.2shared.com/photo/Dj6ZngZI/Sandy_Rock.html

but actually i didn't find something reach for that reality ..
i try it some shaders materials but i didnt get awsome effect at all ...
i try it shaders materials and adding some gemotery rocks above it but also it wasn't that good reality at all ... !!

Also i try it to find some ready texture with sand and rocks but didn't reach for that reality at all ...

i think making oceans or water much easier with shaders

Please if any one have an idea please share it with us !

I would do something like that with the PaintOnSurface plug. Create a good sand texture, of which I've seen many on this forum, and then paint on some rocks, obviously varying the size and placement. You can also do poly paint with hair, although the setup is trickier.

What exactly do you want to do? If it's just a landscape shot, you should just create a nice highrez mattepainting in photoshop. You can just stitch some photos. Then cameramap this image on lowrez geometry.


Cheers
Simon

This was a just a quick test. I don't have the project files anymore but i think i was using this texture from cgtextures in the displacement channel: http://www.cgtextures.com/texview.p...1qqai1kqj41gul4. For more distant shots, use camera mapping as suggested.
