Which pass is the caustics pass

[arlaulhp]

Hello, I want to extract caustics pass,
then apply it to another renderer result

[B.Y.O.B.]

Currently there is no dedicated caustics AOV, but there is a workaround: Set the device to CPU, engine to Path, and enable "Add light tracing". In the light tracing settings, set light path percentage to 100%. Then render.

Is it planned to add a pass for Light Tracing contributions? Is there a technical reason why it is not included in the Indirect Diffuse/Glossy/Specular passes already like PhotonGI Caustics?

I would like to denoise the passes separately but currently am missing the contribution from Light Tracing when adding the passes back together.
