Just having some fun in Blender. I came up with a reasonably good procedural material for a pile of gold coins. It's not perfect close up, but from a distance it looks pretty decent.

while from the top it actually does look pretty decent :) ... it rather looks like a stone from the side though, as gold coins don't fit that perfectly together, except you glued them.
Could you post the texture as well or is there no way to export a procedural material?
Procedural materials can be exported, although you lose a certain amount of detail in the process. What I'll have to do is bake the color, normal, and specular maps onto a 1x1 plane and then export those. They'll be limited by resolution, and they won't tile. The procedural texture can of course be extracted from the .blend file. :)
