Title: Caustics Flicker on animaiton
Post by: VASLAVO on 2023-07-16, 15:37:05
Hy guys, I've been experiencing some issues with caustics on animations, tried different approaches suggested here on the forums with no luck, here I upload two animation samples with the issue, one made wit path tracing on both solutions with noise level of 4 ant the second one with path tracing as primary and UHD on secondary, here I've even increased the photons at 15k as suggested, no luck.

Hi,

I'm not soo sure about the cause of your issue. Personally I would avoid using UHD cache, I would choose Path tracing for both solvers especially when dealing with caustics.

Did you try getting rid of the noise with DaVinci Resolve. It works really well:

Do you have the flicker-free option enabled? https://support.chaos.com/hc/en-us/articles/7777270371473-How-to-fix-flickering-in-animations-

This looks like the caustics pass flickering indeed. Which version of Corona are you using? There were some caustics improvements in V10.
