Trembling background

[Nutrend]

Hi everybody
Would you have any idea how to set the rendering (or anything else) up to remove the trembling on reflective background? I've met such problem even with DOF.

What's coherent ratio?

Hi Aoktar
Thank's a lot for your quick reply. True, I've got used the coherent ratio (0,4). I just rendered a new sequnce and now, with no CR seems to be good.
Does it means that the CR cannot be used for animations at all?

Not exactly. Try with "static noise" enabled. It should be much better.

[Nutrend]

With the same level of CR or lower?

With the same level of CR or lower?

Please make some tests.

Thanks! I don't have time for everythings. Also testing it yourself best way as my opinion and help to understand more.

Hi Nutrend,
off course you can use CR with moving frame, but its better to have static noise ON and set a minimum Samples (ex: 748spp) to let time to Octane to investigate what'is the "coherent ratio".
I can't technically explain better , but tha's sure it is a real time saver when it's correctly set.
