A Geometry Nodes-powered add-on that generates performant rain systems and applies wet surface shaders to existing materials. The tool allows for one-click rain addition with adjustable controls for density, rainfall height, splash intensity, speed, and wind direction. It includes an overlay rain shader that dynamically affects only the surfaces exposed to the rain.

Users can choose between two distribution methods: an accurate area-based calculation for small scenes, and a faster per-object calculation for larger environments. The splash system utilizes rendering points optimized for Cycles. The add-on also includes a custom shader for droplets to simulate motion blur, while loopable animations are supported for creating seamless weather effects.
