This node emits light from a polygonal mesh. All polys must be rectangular. The light is emitted based on quads, so tri-gons or n-gons will not calculate properly. A maximum of 128 polys is allowed.

Lights are generated per poly, so if you tessellate to tris you get 2x lights per quad.

Name Description
Colour The colour of the light.
Brightness How bright the light is.
Scattering Intensity How much the light is scattered in the scene, creating a bright area around the light.
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.
Double Sided Toggle whether light is emitted from both sides of the area light.
IES Profiile This feature is deprecated.
Show Light Cone Show a cone in the scene to represent the lights current position and rotation.


Name Description Typical Node Input
Object Node Input an object from which the light will be emitted. 3D Object
Projection Image Add in an image to be projected by the light. Video Loader
Affected Nodes Choose which nodes are affected by the light node. by default, all are affected. 3D Object
Texture Projection Node Connect a node from which to project the image from. Only functions if an image is being projected from the light. Null
Multi-Source Controller This feature is deprecated.
Transform Modifier Links all transform properties to the input node. Null
Target Node Always faces the x-axis towards the inputs anchor point. Null
Local Transform Override Override the transformation values of the node, relative to its parent. Null


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