I suggest you have a look in full screen mode and in darkness, the purpose of it is to be realistic
(and, it is not well tested yet on different screens yet).
Everything depends on one prop:
- Code: Select all
/environment/darksky-brightness-magnitude
which is the darkest sky brightness magnitude in V band at zenith in magnitude per arcsecond^2. Best skies on Earth go up to 22, that's the setting in the pictures.
In space, no atmosphere, high enough to be above the ionosphere, the moon is around but the Cygnus region is glowing:
Back into the atmosphere, nothing left to see with the moon around... (although it you really looking at carefully, we actually see the dark parts of the Milky Way where stars are hidden by interstellar dust)
But if you wait a bit for the moon to go under the horizon, the glowing is slightly back:
What is going on is that the shaders compute the relative contrast between the intrinsic Milky Way brightness and the dark sky brightness due to moon light diffusion in air as well as airglow from ionosphere.
Examples, the red color traces the darkest regions on the sky:
Half moon just rising. Only towards the zenith the contrast is big enough to see the Milky Way:
A small moon is far less damaging and the sky brightness is really bad only in a halo around the moon:
sky darkness in red:
the same without the red, Milky Way is a bit visible right from the Moon and high enough from the horizon:
Yet some things to improve!
