Hey Guys, for a new project im testing animated caustics right now and i'm actually very impressed and happy with first rnd results.

What i noticed, is a slight light flickering under the surface? Has anybody noticed that?

I've tried to switch from PathTracing+UHDCache to both Path Tracing and increasing the PassLimit, but i still got this flickering?
Thanks in Advance!

Up !

I have many flickering problems too with Corona Caustics.
Is there any solution? Unit cm/cm can be a problem for exemple ?

Hi @TYCHE and @toupan!
We are extremely interested in these kinds of scenes with flickering caustics. Could you please send us an example scene like this? It can be a production scene, or if you are not allowed to share it, or just don't want to, you can try preproducing the same issue in a simpler scene, or remove some parts of your scene while keeping the issue visible. This would be highly appreciated!

We should also be able to provide you with a workaround, which worked in similar cases, but to verify this, we first need a scene where this can be replicated.

You can use the uploader in my signature and after the successful upload, let me know what was your file name.

Thank you in advance.

Hi Toupan, any news here? Did you upload some scene for us to investigate? If so, which method did you use and what was your file name?
Thanks!

We can sign an NDA if you wish. Or maybe you could simplify the scene? (remove 90% of objects and share this version with us)

Hello!

I have the same problem - flickering caustics in my animation. I've attached avi file to this post. Could you please help me with that? I also tried increasing number of passes, but it doesn't work. I can send you my scene if you wish (can you tell me how to do it, please?). I will name it "Animated flamingo scene"
Thank you in advance
