Physical Starlight and Atmosphere

This addon provides a procedural sky and lighting environment based on real-world physical values. It calculates atmospheric scattering, air mass volumes, and sun disk properties to generate dynamic skies. The system includes options for generating primary and secondary suns, alongside procedural or texture-based clouds and stars.

All environmental parameters, including sun temperature, altitude offsets, and scattering coefficients, can be fully animated using keyframes. The tool includes built-in ACES color space calculations and integrates with both EEVEE and Cycles render engines.
