[UPDATE] I actually noticed now that creating a dynamic material instance on the emitter and changing the value DOES actually work…however, it only works on the first emitter in the system and does not work on subsequent emitters. Both emitters are using the same material.
Given that I’m using an event to spawn the burst up in the air where the first single particle dies, I can’t just call the burst as the first emitter in the list. That also doesn’t change the fact that both emitters are using the same material and the parameter is only affecting the first one.
