Re: The flickerfree animation challenge
Sorry, but I don't get it. Please exlude the light tracing issue here (I disabled it for this test) and just focus on the indirect cache. This means, if I rise the threshold, more and more materials should become black. But noting happens. If I rise the threshold to 0.9, which means almost every ma...

Re: The flickerfree animation challenge
I'm working on a better estimation method but FP32 numerical precision is also a huge problem with numbers so large. Thank you for the explanation, I can now understand, why it is flickering and I'm also very very happy, that you are working on the issue. Do you know how other renderer like octane ...

Re: The flickerfree animation challenge
This is the correct behavior, indirect cache is about diffuse and glossy-nearly-diffuse materials (i.e. not specular). So everything over the threshold (i.e. not to "shiny" and "directional") ends inside the cache. Sorry, but I don't get it. Please exlude the light tracing issue...

Re: The flickerfree animation challenge
Another issue, I came across, is that the glosiness threshold of the ind cache does not bahaving like expected. As long as the material´s glossiness is below the threshod the material is not in the cache, it is black in the indirect debug view. If I change the material's glossiness higher than the t...

Re: The flickerfree animation challenge
I have some further question. I don't know if they are related to that flickering. When I hit render in the viewport I get a result, which looks pretty like the normal rendering, in the viewport the caustics are coming very late, meaning after 6s there are no caustics visible in the viewport, but th...

Re: The flickerfree animation challenge
Thank you for fixing the caustics. Regarding the flickering, it is still there. I totally understand your explanation so I rendered it with 4096 samples. This took about 4,5 minutes eache frame. I have a ryzen7 2700x and two gpus (rtx 2060 super and rtx 2060) So do you think there is such a imbalanc...

Re: The flickerfree animation challenge
The flickering is way better, but there is still an increase of brightness. It feels more linear. https://streamable.com/411d7q But what I miss are the refractive caustics. Light tracing and PhotonGI ind. cache is on and persistent. Here is the old flickering version: flickeringversion.png and here ...
