This is still a work in progress and eventually it will end up in an outdoor environment. These are made up of 3 textures, made from scratch with nDo2. I then used dDo as a base for the diffuse before adding my own details to them.
The top picture is rendered in UDK, and the bottom two are rendered in Marmoset. The top screenshot is a more accurate representation of how it will turn out in the end as it has stuff like baked lightmaps and reflections as well as a much more complex and flexible material network.
