Shaders: Principled Volume

Node Interface

Overview

Function	Multi-purpose volume shading node
Nearest C4D equivalent	None

Combines effects from other nodes such as Volume Absorption, Volume Scatter, Emission shader and Blackbody emission into a single node for easy rendering of smoke and fire.

Settings

Note: a * symbol next to the name indicates the parameter also has an input port. A # symbol indicates that the parameter can only be changed with an input node, not in the node itself.

Color*

The volume scattering colour, as in the Volume Scatter node.

Density*

The density of the volume.

Anisotropy*

Skews the angle of the scattered light and alters the appearance. The values range from -1.0 to 1.0. Negative values skew the reflection in a different direction to positive ones.

Absorption Color*

The colour of the volume shadow.

Emission Strength*

This is the strength of the light emitted by the volume.

Emission Color*

The colour of the emitted light.

Blackbody Intensity*

This is a special blackbody emission setting for rendering fire. Ranges from 0 to 1; set to 1 for most accurate results.

Blackbody Tint*

Additional colour tint for blackbody emission. If set to white it has no effect.

Temperature*

The temperature in degrees Kelvin for blackbody emission (as in the Blackbody node).
