I’m new to UE and this is the first time I’ve packaged a game. After installing .Net and Windows SDK I’ve found that some of my Niagara particle systems have a strange flicker whenever one particle occludes another as shown in the gif. This happens in the packaged game as well as in the editor in play mode. However, it does not happen when the editor window when not in play mode.

I foolishly did not make a backup before doing this and also had the new UE 5.1.1 update installed so I’m very unsure as to the cause. The Niagara particles are all mesh spheres. Not sure where to look to get this fixed.
Any help would be greatly appreciated.
EDIT: It appears as though this is happening when any mesh occludes another. I really have no idea what is causing this.
