Setting up the domain
With the Campfire Setup.blend file open, let’s create a domain object and change some of the settings to get the desired look:
- First, add a cube object as our domain and scale it up to fit the campfire. You only need to scale it up to fit the logs, not the rocks. Then, double-check that the cube is tall enough for the flames that you want:

- Once you’re happy with it, head over to the Physics tab and select Fluid. Then, for Type, select Domain.
- As for the domain settings, let’s start by changing Resolution Divisions to
96. This will give us a nice high-quality fire. - With the current settings, the fire will move very quickly in the simulation, so let’s counteract this by changing Time Scale to
0.5. This will slow down the fire. - Set CFL Number to
4. This will decrease the simulation steps, thus decreasing the bake time. - Check the box next...
