I’m creating wheel dust particle FX for a car and I have run into an issue.
I have a Niagara system component for each wheel and I am setting their particle systems using ‘Set Niagara System Asset’, triggered by a line trace and Switch On EPhysical Surface.
When a new surface is detected, the particles associated with the previous surface immediately disappear and the particles for the new surface start spawning. I’d like the particles from the previous surface to remain until they reach the end of their life cycle, and fade out, rather than suddenly disappearing.
Is it actually possible to have multiple systems behaving as I described on the same Niagara component, or does the required behaviour need separate Components for each Niagara system, so they don’t interfere with each other?
I’m new to particle systems and don’t have a clue what I’m doing. I though I’d ask for help before I spend the next week trying to figure this out.
Any help would be greatly appreciated.
Cheers
