TemperatureTemperature controls the climate of a biome. It affects whether it rains or snows, how fast plants grow, and the color of grass and water. Higher values are hotter and drier; lower values are colder.
DownfallDownfall (humidity) is how wet a biome is, from 0 (dry) to 1 (humid). Together with temperature it determines grass and foliage color and whether precipitation falls as rain or snow.
PrecipitationPrecipitation is the weather a biome gets: rain in temperate biomes, snow in cold ones, or none in hot, dry biomes like deserts where it never rains.
