Glowing bright color areas and fire flies in editor

General Feedback & Requests

Have jumped back into UE after a while away. In all projects I am seeing random areas of bright glowing slowly pulsing areas and green firefly sparkles in the editor. This is in all projects I have tried to load.

In the video it shows starting with a new project, new Third Person template, nothing changed, nothing added.

This same behavior is in 5.6, in 5.5, 5.4, 5.2, etc.
I had the latest Nvidia Studio Drivers installed for my RTX 3090, tried Game Ready driver, no change,
Rolled back to Nvidia 566 driver via DUU, exact same result.
I have no idea what to try next.

Thanks for any comments.

Did you by any chance change the make the default wall material smoother?

Zero edits were done, just file creation from template and start play in editor. Starting to think it might be my graphic card failing.

It’s not your GPU, it’s something to do with Lumen, I think, but not sure what…

Is it a default project, no tweaks?

100% stock as created by the editor. Same results if I create it in 5.6 or 5.5 or 5.2.

And a new project does it also?

Have you tried tweaking any Lumen parameters in the post process, like

I mean, you shouldn’t need to, but it might help.

Thanks, the turning off lumen removed the random flashing soft patches of color. The green fireflies are still as strong as ever. Persistant across any unreal project I open, any scene I create.

I ran OCCT VRAM checker on my video card memory. It showed a lot (48K per cycle) of errors during a stress test at 80%, no errors at 50% loading.

I ran Borderlands and there are a lot of artifacts and obscured areas. All indications are that the video card is failing.

Ah, so, two different issues then.

Sorry about your GPU :confused:

The problem turned out to be the video card and the failing VRAM. Changed card and problem disappeared.
