This week I have made a planet model and I spend most of my time messing with its atmosphere. And I researched heavily about atmosphere scattering plus using the image of the Earth sky as its reference.
–The result!
Rendered daytime sky (HDRI)
Rendered twilight sky (HDRI)
All are rendered in 256 samples + compositor denoise + no other post-processing
Node that I made for this result
