Revamped Atmosphere

Previously, the atmosphere visuals were achieved by projecting a texture onto the sky and slowly animating it throughout a day/night cycle, with each frame corresponding to a different time of day. This approach exhibited several caveats. Due to the low resolution of the texture (64x32 per frame), artifacts such as colour banding were prevalent throughout the sky. There were even some downscaling artifacts between frames, with colour from one bleeding into the next (leading to a dark dot near the zenith). BetterRTX solves all of these issues through introducing a physically based simulation of Rayleigh and Mie scattering to render the atmosphere.
