Lighting nodes are nodes that control lighting in a scene. Most emit light from different shapes or objects, but some control how light is emitted or scattered in the scene.
Lighting nodes are generally hooked into the Root node, although they can be applied to any node - they will still appear in the scene as long as there is a path to a Root node, and will just inherit the transforms of the nodes above.
Add a light that applies to all surfaces equally.
Add a light that emits from a rectangle.
Emit light from mesh rectangular Polygons.
Bake lighting on a mesh to preserver render quality and improve performance.
Emit light from an infinite direction.
Generate an environment image for a Skylight.
Add an environment map for lighting.
Add fog to limit view distance.
Add a point or spot Light.
Add planar environment map for lighting.
Add a planar reflection to reflect objects in a scene.
Generate a set of points to improve lighting quality with some nodes.
Emit light from the vertices of a mesh.
Generates a grid of light probes for probe lighting.
Use connected probes for lighting.
Projection an image onto surfaces.
Generate ambient occlusions to improve lighting details.
Generate screen space reflections for reflective surfaces.
Darkens a region of the scene.
Add a dome of light to provide lighting from every angle. Best used with an enviroment image.
Add volumetrics to lights.
Approximate global illumination using voxels.
