MSFSkyType

A gradient between HorizonColor and SkyColor. What the SDK drew before the atmosphere existed; pick it for a flat, stylised or brand-coloured sky.

Rayleigh and Mie single scattering, integrated along the view ray. The blue zenith, the reddening at a low sun and the halo around it all come out of the model rather than out of a colour ramp, so the sky follows the time of day on its own.
