I've created 10 preset vdb cloud volumes that you 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.
PLEASE NOTE: These are not high quality clouds but could still be useful for mid to long range use in your scenes. I wouldn't recommend using these clouds for extreme closeups as their is pixelation still visible on the clouds.
I've updated this project and included a single VDB that has an entire cloudy sky.
I still consider them to be useful so enjoy using the VDB Clouds!
