With latest numerical precision fixes, the BiDir can render large scenes.
3h on e5 2620 v4
I used the "Glare_Layer_vol" for camera vol.
And the hetero volume type with multi / max steps 80 for all.
The step sizes are insane, from the direction of Sun, between Atmosphere_3 and Atmosphere_2, there is close to 600km.
So i divided it by 30 and get 19503.3m, same with others:
Atmosphere_1_vol step size 4926.7
Atmosphere_2_vol step size 10230.0
Atmosphere_3_vol step size 19503.3
Glare_Layer_vol step size 4243.3
Smooth shading seems to not work with that insane scale for Moon, i use shade flat and upped the geometry.
Atmosphere Simulation
Re: Atmosphere Simulation
Moon lighting is not realistic there, because there's (almost) no reflection from earth.
I made the earth to be a complete sphere. Albedo for earth and moon:

Re: Atmosphere Simulation
Super interesting work here!
Yes that blue one has real depth, but also the sunrises (sets?) are great too.

Clouds didn't come out that life true, but still something.
CPU rendered 6 hours at step size 500m, singlescattering.
Another 11 hours at step size 100m, multiscattering.
The first one is much faster, but resolution didn't seem to improve with 100m step size.
BiDirVM and filmic tonemapping. Light tracing seems to not work with this scene scale.
