black flickering/blinking spots everywhere

[Omgitzpeter]

Hello!
Thank you for your attention !
My problem is that, as you can see in the video, there are black flickering/blinking spots. They appear on foliage and static meshes as well.
Any solutions …?

No worries at all! That’s why I’m here

Looks like Z-Fighting. So basically two meshes shares the same space and it makes it flicker as the engine doesn’t know what to render.

If this isn’t the issue, does it help if you disable Anti-Aliasing in the Project Settings > Rendering section?

Also, beautiful scene!

Thank you very much! i’m happy to hear that =)
i will show you final render if you dont mind!

i’ve solved that problem. solution number 1 - is to turn on distance field shadows for all light. and number 2 - to switch dir light to raytraced shadow, and then type r.RayTracing.NormalBias 10 in order to get rid of black spots on meshes.
But at the end i’ve decided to use luman shadows in order to work with vol fog.

Now its been 2 days since i’m trying to solve another issue.
1)Moving shadows, you can see them at the beginning of video.
2) Flashing/blinking highlights when i render with more then 8 temporal sample counts(spatital sample count1)

all meshes set to static and all light set to mov.
in this shot i’m usuing rt shadows with all my light.

Hi!

I know this has been a while but I ran into the same issue on ur last post. My renders in UE5 left flashing white spots just like in your video. Did you find a reason to why thats happening and a way to fix them?

Thanks in advance!
