Volumetric Lighting
Add volumetrics to lights.
Volumetric Lighting
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.
Parameters
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.
Parameter Details
Position X Move along the local x-axis.
Position Y Move along the local y-axis.
Position Z Move along the local z-axis.
Rotation Heading Rotate around the local y-axis.
Rotation Pitch Rotate around the local x-axis.
Rotation Bank Rotate around the local z-axis.
Scale X Scale along the local x-axis.
Scale Y Scale along the local y-axis.
Scale Z Scale along the local z-axis.
Toggle which transform channels should be inherited from the parent node. By default, all transforms will be inherited.
Parameter Details
Position X Toggle inheritance of the X Position from the parent.
Position Y Toggle inheritance of the Y Position from the parent.
Position Z Toggle inheritance of the Z Position from the parent.
Rotation Heading Toggle inheritance of the Rotation Heading from the parent.
Rotation Pitch Toggle inheritance of the Rotation Pitch from the parent.
Rotation Bank Toggle inheritance of the Rotation Bank from the parent.
Scale X Toggle inheritance of the X Scale from the parent.
Scale Y Toggle inheritance of the Y Scale from the parent.
Scale Z Toggle inheritance of the Z Scale from the parent.
World Position Only Inherit the world position from the parent only, rotation and scale will be ignored. Overrides above properties.
Inherit Time Toggle inheritance of time from the parent.
These properties control the core behaviours of the node.
Parameter Details
Sample Density The quantity of volumetric lighting in the scene.
Max Depth Range Maximum distance the volumetric lighting will be scattered.
Uniform Scattering How strong the light scattering is from lights in the scene.
Shadow Noise How much noise is breaking the shadow.
Smokiness the opacity of smoke withing the lights
Smoke Scale The range of the smoke texture within the lights.
Num Depth Slices How many slices of the light field is shown. This is internally limited to 512.
