# vfx-stateless-invalid

> Talos next · Since next

A `*.vfx.json` emitter with `stateless: true` does something that needs its particles remembered: events, a child's role, a spawn other than a constant `rate`, a module other than gravity, drag, sizeOverLife and colourOverLife, or a renderer other than one sprite.
