Living world
Weather and water
Water moves through a simulated natural cycle.
Rain
Clouds carry finite water. Rain removes water from a cloud and deposits the same amount into the world, where it can refill pools, wet soil, and water crops.
Flow and soil
Water flows downhill and spreads across open terrain. Soil and grass absorb nearby water without moving, and wet soil can irrigate crop roots.
Survival
Your hydration pack also uses finite world water. Aim at a sufficiently deep source and press R to refill it.
