It uses a custom render engine specifically made to render real-scale planets. It works in World shader, so it illuminates the environment.
It now supports a multi-layered atmosphere, that receives cast shadows from rings. The atmosphere has an Aerosol layer, a Rayleigh layer, an Ozone layer, and an emission layer. A volumetric Cloud layer is in development.
