Volumetric Lighting

Volumetric Lighting

Add volumetrics to lights.



Method #

Adds a volumetric lighting filter onto the light scattering of light nodes in the scene. Useful for adding atmospheric fog to your scene.

Lights must have some light scattering enabled to see this effect operate.


These properties control the 3D transforms of the node. Transforms will generally be inherited by child nodes, although they can be ignored through the Inherit Transform Channels attributes.

Position XMove along the local x-axis.
Position YMove along the local y-axis.
Position ZMove along the local z-axis.
Rotation HeadingRotate around the local y-axis.
Rotation PitchRotate around the local x-axis.
Rotation BankRotate around the local z-axis.
Scale XScale along the local x-axis.
Scale YScale along the local y-axis.
Scale ZScale along the local z-axis.

Toggle which transform channels should be inherited from the parent node. By default, all transforms will be inherited.

Position XToggle inheritance of the X Position from the parent.
Position YToggle inheritance of the Y Position from the parent.
Position ZToggle inheritance of the Z Position from the parent.
Rotation HeadingToggle inheritance of the Rotation Heading from the parent.
Rotation PitchToggle inheritance of the Rotation Pitch from the parent.
Rotation BankToggle inheritance of the Rotation Bank from the parent.
Scale XToggle inheritance of the X Scale from the parent.
Scale YToggle inheritance of the Y Scale from the parent.
Scale ZToggle inheritance of the Z Scale from the parent.
World Position OnlyInherit the world position from the parent only, rotation and scale will be ignored. Overrides above properties.
Inherit TimeToggle inheritance of time from the parent.

These properties control the core behaviours of the node.

Sample DensityThe quantity of volumetric lighting in the scene.
Max Depth RangeMaximum distance the volumetric lighting will be scattered.
Uniform ScatteringHow strong the light scattering is from lights in the scene.
Shadow NoiseHow much noise is breaking the shadow.
Smokinessthe opacity of smoke withing the lights
Smoke ScaleThe range of the smoke texture within the lights.
Num Depth SlicesHow many slices of the light field is shown. This is internally limited to 512.
