  • In the Fire rollout of the Volumetric Options, select Fuel as the channel the fire color is based on, as this is FumeFX's Fire channel after importing the .f3d file. For Fire Opacity Mode, choose the Use Own Opacity option and carefully duplicate the fire color and fire opacity diagrams from FumeFX.

In order to turn it off and keep only the illumination on the volumetric itself, set the Light Power on Scene value in the Fire rollout to 0.0 and set Self-shadowing in the Rendering rollout to Grid-based. You can also speed up the calculations of self-illumination by reducing the Light Resolution (%) value in the Rendering rollout.
