Rendering Realtime Caustics (Alexander Ameye)
Auto-discovered
Alexander Ameye
Visit resource ↗Description
Alexander Ameye documents a Unity real-time caustics approach using projected textures or light cookies combined with depth-aware sampling, building on his render-feature tutorials.
Explains artist controls, performance pitfalls, and when to fake caustics versus offline path tracing. Pairs with his notes site and GitHub samples used in URP custom passes.
Intermediate Unity shader authors studying water volumes, pools, or glass focal patterns without full spectral simulation.
Widely bookmarked in tech-art Discord circles alongside SSR and planar reflection writeups.
