Takes a scalar channel, preferably containing temperature values to create a buoyant force.

Takes a scalar channel, preferably containing smoke values. This channel is optional.

Takes a scalar channel, preferably a fuel channel or containing fuel values. This channel is optional.

Takes a Duration node in order to define the length of the force emission.

Here you can manually set the direction of the resulting force. By default and probably most of the time used is the Y-Axis

Defines the rising strength. Depends on the temperature values available.

Defines the falling strength counteracting the Rising strength. Depends on the smoke and fuel values.
