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.


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.

ColourThe colour of the light.
BrightnessHow bright the light is.
Scattering IntensityHow much the light is scattered by the light, creating a simple fog around it.
Falloff ModeChange 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 DistanceInner distance within which the light remains at full strength
Attenuation DistanceMaximum distance the light reaches.
Falloff PowerChange how strong the falloff for the light is between the Inner Attenuation Distance and the Attenuation Distance.
Show Light ConeShow a cone in the scene to represent the lights current position and rotation.
