This is a procedural Geometry Nodes system for generating customizable rain and splash effects within Blender. The setup allows users to add weather elements to their scenes without complex manual particle configurations, providing automatic collision and splash generation upon impact with scene objects.

The system includes detailed controls to adjust the visual characteristics of the rain. Users can modify the overall rain density, tweak the radius and length of raindrop trails, and adjust the particle lifetime. Surface interactions can be tuned by controlling bounce strength and the resulting water splashes, making it suitable for atmospheric environments, architectural visualization, and visual effects sequences.
