To create my image, "Ravine", first I created a shaped terrain and tree roots in 3ds Max 2010 and Mudbox 2009 (Fig.01 & Fig.02).

Next, using 3ds Max, I put unwrap UVWs on the terrain (I won't go into detail about this process because it is already available in tutorials on the net!) Then I exported the terrain and roots into Vue 7 Infinite.
In Vue 7 Infinite, I created two extra terrains. Then I experimented with the setup of the terrains, roots and camera angles until I was satisfied with the combination (Fig.03).

In the next step I put a material on the terrain by using procedural materials and layers (Fig.04 – Fig.06).
