This Geometry Nodes setup adds customizable rain to Blender scenes. The generator provides controls for both falling rain and surface splashes.

Users can adjust the rain's droplet amount, scale, fall speed, and the instance object used for the droplets. The rain zone size and tilt can be modified to simulate wind. The splash system includes controls for density, droplet amount per splash, power, speed, and droplet radius. Splash locations can be controlled using vertex groups and weight painting.
