A couple particle issues...

I’m in the middle of making gunfire particle effects including muzzle flash, tracer round beam particle, and impact dust plume. The tracer beam works like a dream, I love it. But the muzzle flash particle only flashes sometimes for some reason, like only when it feels like it. Maybe where it’s supposed to “spawn emitter at location” 50 times it may flash 3 times. And the Dust plume, if I keep the “Emitter loops” at zero it doesn’t auto destroy but at least it appears. If I give it a loop of 1 it just doesn’t show up anymore. Anyone mine giving me a clue? Thanks.

Muzzle flash: set spawn rate to zero, but set burst to 1.
This way whenever its spawned it instantly bursts the particle. be sure to set loop to 1.

as for the dust plumes… no clue, but something has been set oddly.
next time, please make a video and/or images of all important cascade modules.
