Clouds can be constrained to a simple spherical volume with the built-in localization feature. The Density Functions (Density and Final Density) can only accept color input to define cloud density. Objects are not supported for defining cloud density or constraints at this time. But we do hope to have some kind of an object conversion, voxelization, etc. in the future that would then be able to help define a cloud's shape.
