Mod LIGHTING SEASONS BY XKONRAD v1.0 for Farming Simulator 2019
Lighting seasons from xKonrad
   I give you my lighting: P
For a better visual effect, you can use the fog command or something, and you can adjust the brightness of the game: D
Of course, in your game it may look a little different than in my screenshots, everyone is playing with different settings, have different shaders or not at all.
Seasons lets you produce manure and slurry at the same time whether you're feeding straw or not.
