Hello!, this is a mod that adds on to the mod Astrocraft making its skies more realistic!
IMPORTANT: make sure that the version of Astrocraft your using is 1.5.1+1.20.1.
WARNING: the "Horizon color" setting is broken and currently does nothing.
Features: Nodal and Apsidal precession: while it is true that astrocraft adds that it only adds it to moons but this adds to planets too!, Custom Axial Tilts (you can edit axial tilts in the base mod but those tilts are locked and every planet will have the same tilt) + Axial tilt variation: you can choose the axial tilt with a minimum and maximum value and an axial tilt variation period!, Custom Day Lengths + Custom Sky Colors: this mod allows you to have custom day lengths with custom sky colors matching up with the lengths! NOTE: these are solar day lengths not rotational periods, Forest Fire tint: every once in a while forest fires could happen tinting the sky yellow orange or red mostly visible at night.
Planned Features: realistic orbital mechanics: even more orbital mechanics from real life.
