lighting/lumen + AA issue

[frank hawk]

Hi. I'm rendering an image sequence using lumen and AA. Once the render was finished, I noticed that I have a lot of random lights flickering in the scene, like in the example below. The issue gets FIXED if I remove Anti Aliasing from the render settings, but then I lose quality. It has something to do with AA. No issues if rendered without AA. Maybe some CVAR could fix that? I tried increasing final gather etc., but no luck so far. The only thing that worked was to completely remove the AA.

Hmm, I'm not certain but it looks like generic lumen low sample flickering, (there's probably a better term), though if you think AA is causing it I'm not so sure, does increasing temporal / spatial samples affect it at all? Might be related to volumetric fog too, hard to say

I played around with different number of samples, the only thing that removed it was to completely remove the AA

Hard to say what it could be then I'm afraid! Have you tried playing with lumen settings to see if that's the cause?

[frank hawk]

yeah, not much of a difference

Sorry I can't be of more help in that case
