Creating Clouds with Blender 2.8 and Eevee

Clouds are a great example of volumetric shapes. They’re gaseous which means they can’t realistically be modeled with polygons. Instead they’re entirely generated with shader nodes.

Even though volumes require notoriously long render times with Cycles, Eevee makes volume rendering practical. Thanks to Blender’s cutting edge Eevee render engine we can generate, tweak, and perfect cloud volumes in basically real time. 

CHAPTER 1

We’ll start simple by building an uncomplicated  cloud volume based on two noise textures. Then we’ll increase the complexity with a detailed cumulus cloud, followed by cirrus clouds, and eventually building up a complete cloudscape.
