Caustic Flickering Normal / Okay?

[Continuum]

I am rendering a test sequence and the caustics are flickering. There are many objects in the scene moving, so I cannot tell if it is normal? I am using the denoiser, but the glass material is fine. I have used caustics on liquids, with de-noising and there weren't notifiable flickers. Link below.

Are you using caustic cache ?

This problem should have been solved if you are using only light tracing, what version are you using ? Are you using the latest sources ? Can you post a test scene showing the problem ?

There are no-caches in the scene. Light tracing is enabled. I am using luxcorerender-v2.4-win64-sdk. I have attached the exported scene. The images were to big to attach.

You should try to export your scene in text format and use LuxCoreUI v2.5 (or any other tool) to render: as I said, this problem should have been fixed in v2.5.

Okay understood. I was curious if it was normal. I will wait for the official release of v2.5 then. Since it's being integrated into a commercial app I will be lagging behind versions and stick with the official builds. v2.4 working well otherwise.

Thanks for the feedback.
