Note

This light does not illuminate. It operates more like a utility for creating AOVs.

Parameters

AOV Name

The name of the output AOV.

...

If this is on, it produces a RGB color image instead of a float/luminance image for the AOV.

Invert

If this is on, it inverts the signal for the AOV.

...

If this is on, the rays are traced through the glass refractions to get the masking signal through the refraction.

Warning

This will require some amount of samples to get a clean mask or you may use "Adapt All" setting to sample the AOV automatically for a performance degradation sampling all AOVs instead of just the beauty.

On Volume Boundaries

If this is on, the bounding box or shape of volumes will appear in the mask. Since this is not always desirable, this can be turned off.

Use Throughput

If this is on, the values in the mask for the reflected or refracted rays will be affected by the strength of the reflection or refraction.  This can lead to values below and above 1.0. Turn this off if you want a more solid mask.
