Scatter Enable
Enabling this toggle only calculates the data. To visualize and render this data, either Scatter to Diffuse or Scatter to Emission must be enabled.

Intensity Scale
An overall multiplier on the generated scatter results.

Scatter to Diffuse

Write scatter results to the Diffuse Color volume. This can be used to bake a faux color and light contribution from the scatter source volume field onto the density volume. This option can be desirable for fires with smoke and explosions.

Multiply with Temperature
Multiplies the scatter results with the fire intensity volume field to refine the area of effect. Can be desirable with explosions and fireballs where there can be a dark, cooler "crust" around hotter areas of temperature.
