Overview

This node reads in a scatter volume (created by Pyro Bake Volume), which is then processed to control the emission aspect of volume shading.

This node is intended as a building block for building larger volume shader.

Parameters

Scatter

Intensity Scale

Sets the emission intensity for the scatter. Increase this value to make the scatter brighter.

Hot Core Scale

Scales the emission intensity for the scatter where the luminance of the scatter is bright. As the explosion fades off over time, you will see the effect of this parameter less and less even with very large values because over time the luminance of the scatter value is getting less and less. It is good to boost your explosion brightness at the beginning of the explosion. Increasing the value of Hot Core Scale brightens the explosions fissures.

Color Correct

Turns on the color correction controls for the scatter color.

Hue

Rotates the color hue, with values wrapping at 0-1 boundaries.

Saturation

Adjust the color saturation.

Bindings

Scatter Volume
