Thank you Asif!
Which content example number would that be?

I am trying to figure it out as well. I need to Spawn a secondary particle system per particle ID (from the source particles) based on an array.
Hope I am making sense.
That said I am looking at this node as it seems to do For Loop iteration.

So lets say Particle ID 0 = 0 particles spawned
Particle ID 1 = 5 particle spawned
Particle ID 2 = 2 Particles Spawned.
Something like this:

Hi Guys, Did you find any more information as to how this node works? I cant see where to add the function i want applying in the loop and also feed the outputs
Cheers

I got this working, thanks for the example.

Just needed to set the max iteration count, then provide the int for the iteration and remember to increment it yourself each iteration.

@DryRain the MapFor just gives you a method of writing values to the parameter map over multiple iterations so you would plug in the output values of the function to the MapFor inputs.
