Experiment - Sun shader
Added 2020-05-22 12:15:45 +0000 UTCVersion 2 of Celestia's sun, for an incoming small VR scene.
The center sphere is technically a simplified version of a "Cloud Sea" shader that was intended for the RD&Scootaloo scene but never got used.
The corona is made from two VFX system at around 10k particles.
