Flames and smoke rising off a 30 cm burner. The particles carry fuel and are hidden; only the gas shows.

The emitter is a flat burner, 30 cm across, at the 3D cursor. Its particles live a quarter of a second: each gives off fuel round it (Smoke Source, Fuel 1) and is deleted. The fuel burns where it's hot enough, making flame, heat and smoke, and the heat lifts the gas. The particles themselves aren't shown (Viewport Share 0, and not rendered): only the gas.
The bake adds Fire Smoke, a volume object that plays the gas, with the VecFlow Smoke material: flames glow from deep red where they're cool to yellow where they're hot.
Try these first
- Cell Size: 0.04 m by default. Smaller is finer detail and much slower (half the size is eight times the cells). Try 0.06 while you work it out, and the finer size for the final.
- Burn Rate: how fast the fuel burns. Higher gives short, hot flames near the burner; lower gives taller, lazier ones.
- Flame Life: higher for short, licking flames; lower and they last.
Make it yours
- A bigger fire. Scale the burner (an Empty) in X and Y, and raise Edit FlowFlamesBirthPer Frame with it.
- A ready look. The preset button in the Smoke and Fire panel's header has Campfire, Candle and others. See Smoke and fire looks.
- More smoke. Smoke (smoke from each unit of fuel), or the Smoke setting on Edit FlowFlamesSmoke Source.
- Brighter flames. Flame Brightness in the Render Look: no new bake.
- Fire on a mesh. Set on Fire makes the same fire over a mesh's surface.
