This extension is a geometry modifier. It loads a particle file, or reads particles stored internally and creates instances of the selected geometry at the particles positions.
Example of how to create a MaxwellCloner object, add a uv channel, set its custom type to "Density" and enable loading the particle densities arraymodifier, and apply it to an already existing object in the scene.
