I have a caustics_only LPE working, but it's not denoising.

I placed the following in an additionalrendervars lop

Name: caustics_only

Source Name: C.*L

Source Type: LPE


It's working, but not denoising. (I used the Refining Karma Renders tutorial from Side Effects as my test bed)


I'm striving for a denoise solution. For sure, I can render at higher sampling and denoise in post, but I would be taking a bit of a hit.

Is there any way around this?
