- Believable Caustics Reflections (Alan Zucconi)
Believable Caustics Reflections is Alan Zucconi's September 2019 Unity blog post on faking pool-style ripple caustics without ray tracing, sparked by Florian Gelzenleuchter's popular shader GIF.
One tileable texture is sampled twice in a Surface shader at different scales and scroll speeds, combined with min(), then tinted onto albedo with slight RGB UV offsets for dispersion.
The walkthrough covers _ST tiling, _Time animation, HDR albedo above 1.0, and Post Processing Stack v2 bloom.
