Overcast controls the cloud coverage. Higher values result in darker skies and may trigger rain or storms.
Fog affects visibility. Increase for denser fog and reduced line of sight.
Rain occurs when Overcast is above 0.6. Adjust intensity, transition time, and duration below.
Adjust wind speed (m/s) and direction (radians). Direction values range from -π to +π.
Storm events (lightning/thunder) trigger when Overcast is at or above 0.9. Adjust density and lightning interval.
Snow only occurs when Overcast is at least 0.7. Adjust intensity and duration to simulate realistic snowfall.
