**Hello Bobbystahr!**

I saw this in a previous version of Daz Studio and loved the idea. I tried several ways of modeling the background using shapes in Cinema 4D, until you get to stay close to the original. It has several types of backgrounds in Daz Studio, with slightly different shapes created in 3D.
The technique of texture mapping, is all painted in Sculptris, which gives me the freedom to create and paint any landscape, because I can use eg vegetation in PNG format with transparent background. Here is how the final map and compare with some of the very Daz Studio. I hope this clarifies your doubt.
The Freebie is yet to be approved! If so, I'll have new sights for this model.
