In this Blender tutorial, DJ shows how to enable a pre-installed addon called rock generator - now it's a part of a larger addon ‘Add Mesh: Extra Objects’ which may be used for procedurally creating rocks of a different sort (using a preset of sandstone as an example). Every 3d asset needs textures to look good in the final render so in the next step DJ shows a quick and dirty way of texturing your Blender rocks without the need for any UV unwrapping!
Rocks tend to erode and turn to sand (sometimes the other way around as well) so putting our stones in a desert environment seems like a perfect idea for a 3d scene. The last part of the tutorial covers the creation of desert dunes using blender’s ocean modifier and texturing it with CC0 textures. Finally lighting the scene with the new Nishita Sky texture in the World setup, adding sun motion with simple keyframes.
