A Star Trek TOS Effect keeps beaming into my level. What is this?

I am working in 4.26, there is this white glowing effect that is bugging me and I do not want in my scene,. It reacts to bright objects,. Seems to act a bit like a lens flare, if it was a lens flare in the original Star Trek show (ie: it appears to be alive (joke, but does have mitochondrial/organelle-like particles)

Any help appreciated ! :slight_smile:

(Bloom is unchecked BTW :wink:

I think it is a lens flare. You either have to disable it on the post process volume ( if you have one ), or on the camera:
