Photon Kernel - enabling fake shadows cause no caustics?

Hi!

2022.1-XB4(R2)

I found out, that when i tick fake shadows to get proper shadows for specular object, caustics don't show.

I did a screenshot (attached) to show my settings and render result.

Is that known problem or I just missing something?

I've checked in Octane Standalone and same happened - just to see if there is a problem on plugin side.

Cheers,
Kyehoo

Hi,

Nothing "wrong" and no bug here. It is expected in both situations.
This page on Octane's caustics may help.

Yeah, the platonic object was just so thick, that it looked as a solid object from shadow perspective. I've tested with thinner object and it works OK.


Thanks!
