I am working on 3D cobblestons right now. Here is a first result with one texture. Of course I work on several other textures too Stones can be used separately as well as the ecosystem that you see here. Right now I have a dark texture, a moss covered one, a reddish one and a light one. What I want and hold me back from publishing the thing is a wet texture. But it will come (soon).
