noise level

[malindis]

Hello,

I have just a simple question... I have noticed during a rendering that the noise level sometimes goes up again...

Why is that ?

Thanks for the explanation.

Regards.

The question would be, does it actually go up, or did it artificially dip too low?

A small change with it going up might not be unexpected as it gets re-evaluated. However, there does seem to be a bug where it artificially drops too low at one evaluation, then gets re-evaluated correctly - this does show as a significant drop that doesn't match what has been seen in the past evaluations.

You can see the bug report at https://corona-renderer.com/bugs/view.php?id=2811 for more info, and let us know if you are seeing this artificial drop in noise level at some point (that is a drop of 2 or 3% or more, then climbing back up to a more expected level the next time it re-evaluates).

Hi, thanks for this quick reply...

I will continue to check and let you know.

Cheers.

Sorry for reopening such an old thread, but we have some news regarding the issue with noise level fluctuations. According to our tests, and tests from users who reported similar issues, the noise level is now reported correctly, and there are no fluctuations during rendering. We are talking about Corona Renderer 3 Hotfix 2 (currently the newest release), and version 4 daily builds. (for 3ds Max, but the C4D version uses the same core)
