Ambient Light
Add a light that applies to all surfaces equally.
Ambient Light
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
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.
Control the inheritance of the transforms from the parent.
Parameter Details Position Toggle inheritance of the Position from the parent.
Rotation Toggle inheritance of the Rotation from the parent.
Scale Toggle inheritance of the 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 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.

|---|---|---|
| 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. | Loader |
