UE5 Weird "Shadowing" Effect from Emissive objects

Hey, I’ve just noticed that if I move my camera quickly next to/ around an object with an emissive material (in a dark room), then there’s some weird shadowing effect. Please see gif below:

Lumen is turned off, any idea on how to fix this?

Hello Sntfon100, and thank you for posting.

Are you referring to the tiny blue specks?
I was able to reproduce that odd effect myself and found that if I set the Blend Mode to Additive, the tiny artifacts go away.

Here is some companion documentation on material Blend Modes for further reading. I wish you the best in your development journey.

Thanks for the help and info.
Unfortunately, I just noticed that my material’s domain is “Post Process” so Blend Mode is disabled for me. And I can’t change to a different domain since I have systems that depend on it.
