Landscape Material

You can't paint without colors, and you can't build a PCG world without materials! This was pretty simple, I split out a single material into three using the attributes node and combined them using the landscape layer blend node. It worked amazingly!  

Three Terrains

Here I needed to begin with the three terrains I had in mind and go from there. The idea was Ice, Forest and a Desert-like terrain. Between each, I included a blend layer that contained other nature elements to add more visual appeal and help blend between the three primary terrains. My two blend elements were gray rocks between the desert and forest, and white snow clumps between the ice and forest. 

Villages And Roads

Next it was time to start thinking about who inhabited this area. Again, I wanted a sort of naturalist viking-inspired theme, so I downloaded and added a few medieveal wood style homes using a spline interior that allowed me to customize their specific location at the touch of button. In addition, adding the road spline allowed me to do the same, and neither cross one another's path.   

Adding Set Dressing

Another thing that would certainly help this environment feel populated would be to add humanistic elements such as carts, posts, and lighting. Here, I did just that.
