PHYSICAL STARLIGHT SHADER

This addon fills your Blender scene with air (or any gas of your liking) where density at the ground level is the highest and in the space - lowest, then a Star of your choice illuminates the air using physics laws - easy as that!

Lighting is calculated based on Rayleigh theory of light scattering through gaseous and liquid medium. Most critical part of the calculation is the fog. Like in real world, it changes based on altitude of observer.

Although my work is based on physical functions and research, my usual approach is to stick with what looks right. That's why there are some 'artistic' liberties taken (or rather, manually fitted values based on reference images) to make it stand out from the crowd.
