Any idea what this flicker is?

Hi all,

I can't figure out where this flicker is coming from.

I tried with IRR-LC and BF-LC.
I get the same flicker, only on the chair an painting, seemingly.

what shader you have on them? no interpolated glossy or anything like that?

[Lupaz]

No. In fact, they don't have reflection at all. They have a simple vraymaterial.
They had a bump map but tried without it and get the same flicker...

Are you using a saved light cache? If not, try that, or alternatively try turning on the "use camera path" option of the light cache.

I was using a saved LC when using Irradiance map. Should I tick "use camera path" if I calculate the map with "fly-through"?

No, there's no need. In that case it would be best if we can take a look at the scene; you can send it support@chaosgroup.com

Thanks.
I increased AA samples to 100 and noise threshold to 0.003 and it fixed it pretty good.

It was probably the HDRI without enough subdivs. I don't know...
