Niagara beam produces artifacts when intersecting

Hope this question fits in here (I’ve contemplated ‘asset creation- fx’ as-well)

Hi all!

Lately I’ve delved deep into UE5.3 so to create real-time visual effects.

Till now I’ve used Aftereffects and blender (cycles) , so I’m not proficient with real time engines,
But I am studios and very stubborn, so once I got the real time bug in my head it didn’t leave!

My problem is I’m using Niagara, which I know little about, and the closest thing I used to a particle system was ‘particular’ for AE.

I followed this tutorial here → UE4 Niagara Tutorial - Laser and Niagara Parameters

it was amazing and informative, as I wanted the laser to shoot out and move like show lasers, and all I know is a little blueprints.

Than I’ve noticed that when the beams cross, unlike in ghost busters, it just creates artifacts.

I assumed this was because of a lack in knowledge in Lumen, as it’s a new system even in the UE sphere of knowledge, but turning it off helped only a little, so I looked around the web and got to thinking that maybe it’s something to do with antialiasing? it was a long shot but I tried switching to FXAA to no avail.

at some point I just assumed this is some kind of overlay problem, like maybe the glow around the beam is trying to affect whatever’s beneath it but what’s beneath it is also trying to add on top of that and that somehow created an error?

or maybe Niagara creates a plane to draw the ‘beam’ upon and since I move the beam it has to redraw it every time and the artifact stems from UE weaving all the beams together while drawing them to save on resources?

But these are all amateurish guesstimations based on gut feeling and experience in a different field, Fact of the matter is I’m too new to UE5 to grasp why this could happen and I haven’t found a real solution by googling “Niagara beam artifacts”

any ideas or even leads to why such a thing could occur?

thank you in advanced to all would be helpers!
