After recently learning something new about Blending Shaders, I have put together some changes to some previously released Fake Stones. Here are some of these library files updated with the new changes. Hope you enjoy these. Rip 'em apart and learn or just use them in your renders.
It's time for a rock library, isn't it? Welcome to everyone to put your rocks surface TGCs and fake stone TGCs here. Please come aboard.
Here's an update to the 'bigger-stones' TGC.
Boulder's TGC altered. Enjoy. ;D
Changed pebbles...
Here is a rock clip file that I've been building for a while. At certain times, they come out looking incredible. Other times, just marginal. I also have other sizes I've been trying to dial in. Unfortunately I've found its not as simple as scaling the settings up or down.
Anyway, enjoy the file. :)
Small Stone Clip File altered.

here is a quick and dirty test using some voronoi as displacement....have fun dissecting this!
cheers

This is a set of 8 fake stone shaders racked up to give complete coverage of a surface that you can control via a surface layer or distribution shader. The fake stones range in shape and scale from .01 meters - 1 meter, respectfully.
I've had the common problem of small, lower stones displacing the surfaces of larger stones above them for a while. This method eliminates that problem.
It is based on FrankB's suggestion of using a merge shader's 'choose by altitude - Highest (raise)' method http://forums.planetside.co.uk/index.php?topic=3796.msg41840#msg41840 (http://forums.planetside.co.uk/index.php?topic=3796.msg41840#msg41840) to merge 2 fake stone layers together without the bleed-through from below. A fantastic tip, thanks!
I've used this idea to the power of 7 merge shaders, combined into one surface.
For the correct way to wire this to your scene, just add a new surface layer to the end of your shaders list, uncheck apply colour and stick 'Final Merge Shader' into it's child socket(example image attatched). Now just use the surface layers distribution parameters for control.
Hope you have fun with them!
P.S: The textures here are designed for an algae-covered riverbed(as that's my latest old haunt I'm revisiting ;)), just change the 4 'stones texture' colours/displacements to suit. The scales are all good, I think, so they probably don't need much tinkering there.
The larger stones might need a little more displacement as I can see some sharp edges/corners...

Here's a streamlined version of the above. Just one surface layer to drop into any scene. All the settings are networked internally.
Pop it onto the end of your shader-tree between your last ground texture and your planet and just use its constraint tabs for distribution.
An entire rockbed in one surface layer, nice! ;D
It would be nice if the "Add Terrain" and "Add layer" buttom had an assign shader option, for inserting complete layers like DandelO's
I'll second that!
An option to add a clip via a 'load from file' item in the bottom of the 'create' items context pop-outs.
I'm building up a library of preset shaders and TG operations, 'insert clipfile' is great but it would be better to have the option to add a specific item in the rightclick menus. It would obviously still be clipfiles as TG doesn't save shaders and things specificaly, but a good idea anyway in my opinion.
dandelO - Great submission! Woohoo!!!
...and inkydigit, too!! Cool!!!
waa.. T_T
Mine dont work..is this right?

it does not show on my terrain...

Not too sure but try plugging it into the Child node ...

That's right, Richard. The final merge should be set as a child to a surface layer. Or, even easier, download the streamlined version in the post after my first. Then you just need to plug your shaders into the input and then its' output to the planet.
Your going down maggot!
All we had was a weedy field. It was great!
Wow ram7.... that spam nearly bored me to death for a moment...
Can someone make rocks suitable for use as asteroids?
Calico can, I think... ^^
Otherwise, just use a displaced sphere or planet.
Never mind, I made some myself. You might need an asteroid texture map called asteroid2.jpg for it to work properly. I'll upload a couple:
I never quite finished the example image. I'm still working on it and I might have to Photoshop in the explosion if I don't get the light source to work.
The maps came from Celestia, an excellent 3D space simulator: http://www.shatters.net/celestia/
There is a program around here somewhere that I wrote to auto-generate asteroids. It can be sort of weighty on the system, depending on your settings. ;D
Hi folks, just messing about with some fake stones again, came up with this...
have fun!

Kaiser Prime Planetary Rocks (stones)
these are the rocks i used for the deviation below. they are fully adjustable and can be modified to your liking
