This tutorial gives a step-by-step approach on how to render the Walt Disney Animation Studios Cloud Data Set. The VDB files contained within the download are heterogeneous volumetric cloud model containing density data. We will render this VDB data using an Arnold Volume and shade it using a Standard Volume shader. We will light the scene using a physical_sky connected to the color of a skydome_light.
Once you are happy with how the cloud is looking, you are ready for final frame rendering.
