Math behind PhysicalSky [CLOSED]

    I'm currently trying to extract the sun angle (azimuth, elevation) from the physical sky object. (In particular the sphere object inside the gizmo)
    I used the general approach via Lat/Lon, Julian Date, leap year, Eclipsis, Sun Declination, equation of time, etc.
    While doing that, I realized that the Physical Sky behaves different from what I expected.

    My calculations seem to be correct (Decl, EqT are all correct), but there is a slight offset that I'm not able to eliminate.

    Is it possible to provide the formulas and/or constants that are used in the calculations for the Physical Sky object?

    Thank you,

    Hi Robert,

    I'm sorry, but SDK Support is not allowed to disclose any C4D internals.
