wierd artifacts in animation

[alexworx]

Hi all,

I am getting weird artifacts in my animations of this scene. Not sure if I need more samples in the LC?
I render out a small clip every 5th frame to show off what I am trying to explain. You can see it on the tables and the beams.

I am using BF and LC.

Thanks, guys.

Does it help if you turn on "Sub-pixel mapping" and "Clamp output" in the Color mapping section of the render settings?

Is this with denoiser?

[alexworx]

So I tried turning on subpixel mapping and clamp output same results as before. Yes its using denoiser.

Do the original RGBs have these artefacts?

[alexworx]

Yes they do

Can you show the originals? Because of the video compression it's a bit hard to see what's going on.

Best regards,
Vlado

Vlado here is a link to the animation...its only 60 frames every 5th frame is rendered but you can see whats going on.

are you using lightcache for glossy rays.? if so turn it off and see if it helps.

Dmitry I tried that as well and got the same results. What I did today was I turn off LC and used BF in both primary and secondary and def got rid of the issue. So now I am testing a higher subdiv with LC and see if thats the issue.

So I decided to try BF in both primary and secondary and that worked in getting rid of the artifacts but its very noisy. Sort of running out of time in trying to figure out why the LC is producing the effect.

Tried LC at 3000 and retrace at 8.0?

I did Ashley and still no luck
