Im wondering how i can change all particles of an emitter during its life time. For example i want that all spawned particles change the size at the same time no matter if its exist for ten seconds or its just spawned.
You can use an InstanceParameter and an Actor or Level Blueprint to manage this.
The tutorial covers changing color and location, but you can use a SizeByLife module to do the same with the scale of your sprites.
I hope that helps!
thx a lot, i over looked the tutorial and im pretty sure it will work. I will try it when im home
