LPE caustics only is not denoising July 26, 2026, 7:27 p.m.

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?

Render curves as flat ribbons with Karma XPU Sept. 14, 2025, 10:04 p.m.

Yikes! Is it still this way with H20.5.684? I know that renderman from solaris can do ribbons (as long as you include an N attr)


yup, still that limitation. just checked.
