Example for a custom Particle System VFX?

I'm trying to add a new rifle ammo type. I based it off a Shatter Rebar (inherited from it) and put it inside of a Rifle. It works, but there's a visual issue: pellet traces are being drawn not from a rifle's muzzle but from a pioneer's right ear. I can enable my rifle ammo for the rebar gun too and there it draws traces from the muzzle. So the issue is with the weapon model then? But what could it be? Both the Rebar Gun and the Rifle have muzzle socket in their meshes. Traces VFX doesn't use that socket, apparently. Then i tried to bind to Event Play Effects, which receives an array of hit results for each of the pellets. Hit results have fields (among others) Location, TraceStart and TraceEnd. I had an idea to edit TraceStart before calling the parent function, but i discovered that the parent function doesn't use TraceStart. It uses TraceEnd for the end point of a trace VFX and Location for the dust VFX at the impact point, but not TraceStart (or any other field from the hit result). So i have no idea what it uses as a start point and i can't control it because it doesn't take it from the input array. So then i decided to create my own VFX and play that in EventPlayEffects instead of calling the parent function. But that's where i'm stuck currently. I watched a couple of Niagara tutorials and made a test particle system, but i don't see any visuals when i spawn it in the game. Muzzle flash VFX isn't even a Niagara particle system, it's a legacy Cascade system, so i'm not sure if i should use Cascade too or if i should use Niagara. So, has anyone managed to create a custom particle effect in a mod that has open source that i can study? Or maybe other tips regarding rifle shot traces.

Solution:

I'm cooked, nevermind. Niagara works, just like cascade. I was trying to use the wrong variable.
