Grab a free pack of VDB cloud volumes by Travis Davids that can be used to set up a nice sky. The set is compatible with any render engine that supports VDB, like Octane Render, Redshift and Arnold.
I’ve created 10 preset VDB cloud volumes that you guys can use with your scenes. These are basically 3D clouds that you can use in your scene. They could even be used as ground fog. They can be used with any render engine that supports VDB, for example Octane Render, Redshift and Arnold.
