Volumetric Light Issues

Hi everyone, hope you’re all well.
I’m having some trouble with a volumetric light in the scene I’ve created for a cinematic.
It has these orb like things appear when I try to render it out and no matter what light setting I have or console variable during the export they are still there, but not during the edit. See images attached.

These are the console variables I’m using in MRQ:

r.VolumetricFog 1

r.VolumetricFog.Distance 1000000.0

r.VolumetricFog.GridPixelSize 2

r.VolumetricFog.GridSizeZ 256.0

r.ViewDistanceScale 5

r.VolumetricFog.TemporalReprojection 0

If anyone has any ideas how to fix this I’d be very grateful.

Thanks in advance
Best wishes

Rubin
