HDRP – Wet Shaders : Rainy 3D Objects

Create realistic dripping raindrops on 3D objects, improving the visual of any rainy scenes in real time.

Raindrops are generated automatically, and each raindrop falls at a random rate, preserving any visible repetition.
Move and rotate opaque or transparent objects where you want in your environment, the raindrops will always fall down.

Supported Unity versions
