Niagara: fade particle based on time

Hey guys,
I’m creating a set of particle systems for my projects.
In Niagara how can I fade particle based on time or age?

should I do that in material editor or Niagara System please?

If you check out some of the Niagara emitter templates(Hanging Particulates for instance) they have a Scale Color module in particle update section. They are set to adjust the alpha of the particles over time(particle normalized age) but the curve is set to start as 0, climb up to 1 then back to 0 to fade away. What you need to do is change that curve times&values as you like. Also make sure your particle material uses Particle Color alpha for opacity if you are using your own material.
