pops

Important thing to remember with pop replicate

# the source particle will be added to the replicated stream

Normalized age of particles:

@age =  Time in seconds since the particle was born. To get the relative time, useful for fading effects, use @nage.

@life =  Time in seconds the particle is allowed to live. When @age>@life, the particle will be marked dead.

@nage (inside pop network) =  @age divided by @life. Implicit attribute, you cannot write to this.

of-course we can make a custom attribute for normalized age (age/life) and utilize it.
