What is this?

This is a rainbow crystal cave scene to showcase a screen space refraction shader, a flow map shader and some water caustics made in Unity with shader graph. Made as part of Harry Alisavakis‘s ‘Rainbow’ challenge on his discord which was one of my suggested themes! 🌈


  • Screen space refraction
  • Animated flow map
  • Animated triplanar water caustics
