Lighting AOVs


A Lighting AOV isolates the light source's contribution. Each light pass behaves as if all the other lights in the scene are switched off. You can combine individual lighting passes together to recreate the original render in post, or to further adjust the individual contributions of each light during post. There are three categories of lighting AOVs:


The following lighting AOVs are available for each of the three lighting categories of AOVs (Figure 1):

To use lighting AOVs in OctaneRender®, you need to identify and map each light emitter to the desired light pass by adding the Octane OBJ Spare Parameters node to the Emission objects.

In the Light Emission, tab you can assign the Light Pass ID for that object (Figure 3).

This can also be done by assigning the Light Pass ID in each of the emission nodes or Octane lights that are in the scene (Figure 4).
