Description

SIGGRAPH 2025 Advances: STOCHASTIC TILE-BASED LIGHTING IN HYPEHYPE is a SIGGRAPH Advances in Real-Time Rendering talk by Jarkko Lempiäinen of HypeHype on mobile-friendly many-light shading for a UGC platform.

It motivates bandwidth and tile-based mobile limits on low-end phones, contrasts tiled deferred scaling and bandwidth-heavy ReSTIR with per-tile stochastic light sampling shared across pixels for coherent pixel-shader evaluation. The talk covers unpredictable light spawning, kitbashed prefab lights, fp16-friendly design, and consistent quality from budget Android devices to high-end PCs.

It is for advanced real-time lighting engineers targeting mobile GPUs and UGC engines where artists cannot manually budget light counts.

Access is a free YouTube recording on the SIGGRAPH Advances in Real-Time Rendering channel.

It is useful as a production case study of stochastic tiled lighting tuned for tile GPUs rather than desktop ReSTIR-style pipelines.
