Hello! 
This is my first attempt at creating an asset pack, it contains 5 Pebble Meshes Each With 2048x2048 Diffuse,Specular and normal maps.
All meshes created entirely with blender using the rock generator add-on, displacement modifiers and sculpting.
Textures made using a combination of Blender, PhotoShopCS5 and Xnormal.

^^ Sorry for not posting the download here, the file size is way too large due to the texture maps 
The pack is in the form of a .Blend file and a texture folder (Compressed in a zip file). I tried packing the textures into the blend, but the shaders stopped working correctly for some reason, So i had to settle with just bundling the texture folder alongside the .blend in the zip file and making all paths relative.
The Pebbles Are relatively low poly… The vert counts are as follows;
Pebble 1: 1,538 vertices Pebble 2: 2,306 vertices
Pebble 3: 1,538 vertices Pebble 4: 1,410 vertices
Pebble 5: 2,306 vertices
Feel free to use these models in any way you want, modify them, change the textures etc, just don’t add these models to a paid asset pack, i want them to remain free for anyone to use
If you feel like you could use these in a free asset pack, then let me know via e-mail (My e-mail address is in the README file of the download)
Here is a quick test scene i created with the pebbles, using the hair emitter to add a few thousand pebbles to a plane
And here is a wireframe render. All meshes are 100% Quads.
At the moment, the shaders are grouped, with no user-input options. But they are organised neatly, so shader modification should hopefully be relatively easy Just open up the node groups and have a play around with them 
I have only tested the shaders on v.2.77 rendering with cpu, So i hope they work well on previous versions too
Please let me know if you find this pack usefull, or if there is any problems with the download/.blend/shaders etc, Thanks!
