Ambient Light

Add a light that applies to all surfaces equally.

Method #

This node emits a uniform light onto every surface in the scene. Useful for adding a little bit global illumination by raising the lowest levels of brightness in a scene.

This is a great tool for adding light to dark and shadowed areas.

All nodes connected to this node are treated as if flowing to the parent node, and inherits any transformation changes along the chain.

Parameters

Transform

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.

Inherit Transform Channels

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.

Attributes

These properties control the core behaviours of the node.

Parameter	Details
Colour	The colour of the light.
Brightness	How bright the light is.
Scattering Intensity	How much the light is scattered by the light, creating a simple fog around it.
Falloff Mode	Change how the light falloff is calculated. Inner / Outer Radius (Legacy) : light falloff is calculated between the inner and outer radii. Inv-Squared Distance (Physical) : the light falloff is calculated based on a physically accurate system.
Inner Attenuation Distance	Inner distance within which the light remains at full strength
Attenuation Distance	Maximum distance the light reaches.
Falloff Power	Change how strong the falloff for the light is between the Inner Attenuation Distance and the Attenuation Distance.
Show Light Cone	Show a cone in the scene to represent the lights current position and rotation.

Inputs

Name	Description	Typical Input
Projection Image	Add in an image to be projected by the light. Only functions with deferred rendering enabled. Useful for adding gobos to lights, or making a simple projector light.	Video Loader
Affected Nodes	Choose which nodes are affected by the light node. by default, all are affected.	3D Object
Texture Projection Node	Controls the direction the image is projected from, independant of the light. Only functions if an image is being projected from the light.	Null
Multi-Source Controller	Depreciated feature.
Transform Modifiers	Apply the transforms of another node to this node.	Null
Target Node	Modifiy the rotations of the node to always direct the z axis towards the input.	Null
Local Transform Override	Apply the transforms of another node to this node, relative to its parent.	Null
