Mapping

Select the simulation channel that you want the shader to use as input.

Blur the field before using it as shader input.

You may want to remove all smoke from the region where fire is shaded to allow for a clearer flame. This value specifies the mapping intensity above which fire will erase smoke for shading.

This function curve (f-curve) allows you to map the input values to an intensity curve before they are used to determine the fire color and opacity. A linear 0 to 1 gradient will leave the values unchanged.

To edit the Mapping, click on the curve to open the f-curve editor. See the section on using the f-curve editor for details.

These parameters let you use a separate input channel for fire opacity. If used, the above input, smoothing and mapping parameters will only affect the fire color.
