Description

Procedural underwater caustics that ride on a light.

Drop this material into any Spot or Directional light's Light Function slot and it projects the rippling, focused light you see on a pool floor, a flooded corridor, or an ocean bed animated, seamless, and generated entirely in-shader.
No textures. The caustic web is built from a two-octave animated Voronoi pattern, so it tiles forever, never loops, and ships as one self-contained graph you can paste and read end to end.
Prefer your own art? Flip one switch to bring your own caustic texture
Required setup: create a Material, set Material Domain = Light Function, paste the graph, wire the result into Emissive Color, and assign it to a Spot or Directional light's Light Function Material slot. Tune the light's Light Function Scale for on-ground size. Best on Spot and Directional lights; Point lights project it spherically and read weakly.
