This asset provides a procedural rain setup using a combination of a geometry nodes modifier and a custom shader node group. It allows users to add rain to a scene without relying on physics simulations. By assigning a collection of objects to the collision input, the rain will interact with the designated environment geometry automatically.

The system is highly customizable through Blender's standard panels. Users can adjust the coverage area by scaling the emitter plane in Edit Mode. Physics-like properties such as rain count, direction, and randomization are controlled in the modifier tab, while visual settings like rain speed, opacity, and color are managed within the shader editor.
