GPU Fireworks (Patreon)

GPU Fireworks is a high-performance, fully GPU-driven fireworks system designed for VRChat worlds. It allows you to create large-scale, visually rich firework shows with minimal setup, while still offering deep customization when needed.

Works on PC, Quest and other mobile devices!

This is not a simple firework particle prefab. GPU Fireworks is a modular system that lets you combine fireworks, rockets, controllers, and timers to build complex visual effects.
