We’ve been working on NixieFX, a browser-based particle and VFX editor aimed at HTML5 games.

Effects are authored visually and exported into the game project. The open-source runtime uses one deterministic particle simulation, with Three.js and PixiJS renderer adapters.

For Three.js, the basic lifecycle is deliberately small: load the exported bundle, create a ThreeVfxRenderer, instantiate an effect, update it once per frame, and destroy it with the owning scene.

The editor can be tried here:

> **[NixieFX — Particle & VFX Editor](https://nixiefx.com/editor/)**
>
> Create, preview, and export particle effects for Three.js and PixiJS web games directly in your browser.

Three.js integration details:

> **[NixieFX Three.js runtime — guide and API reference](https://nixiefx.com/threejs-runtime/)**
>
> Everything the nixie-fx Three.js adapter exposes: loadVfxExportBundle, ThreeVfxRenderer, effect instances, providers, runtime controls, stats, and performance guidance.

Runtime source:

> **[GitHub - azakhary/nixie-fx: Open-source particle and VFX runtimes for PixiJS...](https://github.com/azakhary/nixie-fx)**
>
> Open-source particle and VFX runtimes for PixiJS and Three.js

I’d be particularly interested in feedback about the runtime API and export format from people who have already integrated particle systems into Three.js games.
