Description

Rain Effects Breakdown (July 2023) is a Cyanilux walkthrough pairing Shuriken rain with Shader Graph ripples, puddles, and rain-on-surface shaders.

Particles use stretched billboards in a scaled box with URP or Built-in unlit materials; VFX Graph is noted for URP or HDRP. Ripples use custom HLSL baked to a flipbook normal map via BakeShader, then sampled on a Lit water graph. Simple raindrops use Voronoi dots and scrolling noise; a complex section adds Rainy Window normals and Scene Color refraction.

For intermediate Unity artists using Shader Graph Custom Function files; Built-in opaque texture and HDRP Scene Color caveats appear for glass distortion.

Free on cyanilux.com with sections for particles, ripples, simple and complex raindrops, plus an optional ripple flipbook.

Useful for stylized rain; Cyanilux posts are often cited in Unity shader communities beside official docs.
