Warped Dunes

Working on a short tutorial on how to have rock formations alter the shape of dunes. Will publish it next change I get.

The basic idea is to mix two separate terrains (Dunes and Rock formation) with 100% Max mode in Combine, then use the Separation mask to drive the displacement of the dunes.

This tutorial will also cover an important concept I like to call "Intentional Orphans". This is where nodes are used for something other than their primary output.
