Dev Implements Boundless Hash Grid Fluid Simulation in VRChat

Michael_Moroz_ · x · 2026-09-10

Developer Michael Moroz implemented hash grid-based fluid simulation inside VRChat, with impressive results. Because it's hash-based, the simulation is literally boundless — fluid can occupy the entire world.

Particle rendering is currently limited to a 'Mentos'-style effect; isosurface rendering is the next step.
