Interesting! I will try this on a recent project where I couldn't avoid some noise...

Well, this does work, but it pretty much turns off reflections everywhere, and would require a lot of adjustments in the materials to get everything to look right. It also doesn't fix the same issue with shadows. I discovered you can fix the shadows by selecting your Post Process volume and increasing the Lumen setting "Final Gather" to 3. This was the best performance vs quality setting for my level, but you'll have to adjust to suit your own needs. Somewhere between 3 - 8 works, but you obviously want the lowest number possibly as it greatly impacts your FPS.

Of course, final Gather will help with overall look of the scene, thanks for your contribution! Also for shadows if you are using ray traced shadows you can also increase the "Sample per pixel" setting in your light sources. Such as directional, skylights, etc. This is really helpfull to reduce noise on soft shadows but must be used carefully as if you increase it to much , you will lose a lot of performance.

Nice workaround, but unfortunately although it does remove the problem, it looks like it removed that round reflection totally, and it does not produce accurate reflection.

Hi there ! you are absolutely right, unfortunately with lumen we still have to make some concessions (specially on reflections) want it or nor with its current state, this is most likely related to the emissive material of the pendant light, we hope that in future UE versions this workaround will not be necessary. But we consider that what is gained is much more than what is lost, especially being a satin material where the reflection is not totally clear. Thanks for watching and giving your feedback!

@@EliteRendersAcademy-ES Totally got it, it is good way to get rid of it in the most of the situation, and until they find the way to fix it up. Cheers

The noise is happening because you are using DLSS or other upscaling system with a low percentage screen resolution. (something like 50%). If you are using any upscaling method, make sure your screen percentage is set to 100 or if using DLSS make sure to use DLAA method. Obviously, this will affect your performance, but for the final render is totally worth it.

Hi there!. Thanks for watching and for your feedback. Its using the default TSR AA method , 100% screen percentage and high sampling values in the post process volume. This flickering noise is specially visible for metalic materials even using a bigger than 100% screen percentage and cinematic scaling options.

Mmmm that's odd. I being dealing with this issue for a long time. And atleast using TAA at 100% or DLAA with DLSS fix it. And yeah, is most noticiable at certain roughness levels and with emissive surfaces. And I was able to solved it .

@@ProjectFightsame thing happens to me as well, after start using 5.4 version I’m seeing these flickers issue all the time and doesn’t matter actually what settings you set before, I’m assuming that problem mostly because lumen.. on 5.3 we had a standalone ray tracing which is fix all that things. BUT! I agree with that we need to control roughness level and normal level, if roughness amounts are crazy than flickering will happen again :)
