Re-up my Zawarudo with Gate of babylon (sci-fi) effects.

Setup example, it works with spawn rate also.

This is the Decay attribute, you use it to control post-lifetime behavior of infinite particles.
I got some references from @Guraoz

I make a simple script where you can control infinite particle post-behavior. Say, you want to spawn one particle and control its behavior after it reaches a certain lifetime or its lifecycle slider elapses. It helps me smoothening out the effect (like using dissolve) instead of it flashing-out.
