Sets rain density smoothly over the given transition time. A transition time of zero means an immediate change. A rain density of zero is no rain, one is maximum rain. Rain is not possible when overcast is less than 0.7.
Arma 3
Since Arma 3 this command is multiplayer synchronised:
  • If executed on server, the changes will propagate globally.
  • If executed on client, the effect is temporary and will soon change to the server setting.
Minimum overcast needed for rain in Arma 3 is 0.5.
Prior to Arma 3, each client and the server could have different rain values.

Syntax 1

time setRain rain
time: Number - Transition time in seconds to the new value
rain: Number - New rain value in range 0 to 1.
Return Value:

Syntax 2

setRain rainParams
rainParams: Array - array of custom RainParticles params, see rainParams. Use empty array [] to reset to default config values
Return Value:

Syntax 3

setRain config
config: Config - config path to a custom class, which contains RainParticles class. Use configNull to reset to default config values
Return Value:


Example 1:
60 setRain 1;
Example 2:
Force no rain:
Example 3:
Snow like effect (Since Arma 3 v2.08):
0 setOvercast 1; 0 setRain 1; 0 setFog 0.1; // snow affects visibility at distance setHumidity 0.9; // don't want to see dust clouds enableEnvironment [false, true]; // don't want to see snakes and butterflies either forceWeatherChange; setRain [ "a3\data_f\rainnormal_ca.paa", // rainDropTexture 1, // texDropCount 0.01, // minRainDensity 15, // effectRadius 0.1, // windCoef 2, // dropSpeed 0.5, // rndSpeed 0.5, // rndDir 0.02, // dropWidth 0.02, // dropHeight [0.1, 0.1, 0.1, 1], // dropColor 0.1, // lumSunFront 0.1, // lumSunBack 5.5, // refractCoef 0.3, // refractSaturation true, // snow false // dropColorStrong ];

setTimeMultiplier does not affect transition time.

Using Example 2 on dedicated server might need additional interference on JIP clients. The reason is that JIP has rain value > 0 slowly changing to 0. To force client to sync one can execute this on client:
