Weather Configuration Guide

Important Notes

  • This configuration should be placed in your cfgweather.xml file in your server directory
  • The reset parameter allows you to load weather from storage instead of using this file
  • The enable parameter determines if this configuration is active
  • Weather conditions like rain require minimum overcast levels to appear
  • For Chernarus and Livonia, snowfall should remain at 0.

Weather Parameters Explained

  • Overcast: Cloud coverage level, affects ambient light and weather conditions
  • Fog: Visibility reduction, can create atmospheric effects
  • Rain: Precipitation, requires overcast threshold to appear
  • Wind: Controls both direction and strength of wind
  • Snow: Usually set to 0 except on winter maps
  • Storm: Controls lightning properties and frequency

Common Settings

  • Sunny Day: Low overcast (0.1-0.3), low fog, no rain
  • Cloudy Day: Medium overcast (0.3-0.6), light fog
  • Rainy Day: High overcast (0.6-0.9), rain enabled
  • Foggy Morning: Medium overcast, higher fog (0.2-0.4)
  • Stormy Weather: High overcast (0.8+), rain, high wind, storms

Understanding Parameters

  • actual: Current target value for the parameter
  • time: How long it takes to reach the target value (in seconds)
  • duration: How long the value stays before changing (in seconds)
  • min/max: Absolute limits for the parameter value
  • timelimits: Range for transition times between values
  • changelimits: How much the parameter can change each transition
  • thresholds: Required overcast levels for rain/snow & time to stop if conditions aren't met

Weather Server Performance

For better server performance, avoid rapid weather changes (use longer transition times) and extreme conditions like heavy fog or maximum wind speeds. Balance between realism and playability for the best experience.
