Take a journey into the desert with this video course on procedural creation in Blender 2.8! You will learn a flexible workflow for building realistic sand dunes. Let Blender do more of the modeling for you with procedural texture displacement and adaptive subdivision (micro displacement). Finish off the final render with a touch of compositing treatment.
