PFlow Particles not emitting smoke over time

[jrand]

Exactly, PFlow assumes that a particles lifespan is a ludicrously high number by default, I actually believe it is in the neighborhood of the maximum time duration in max. You can set it easily with as you figured a Delete Operator, or a Script operator or a Box#3 Data op.

Take note that this is useful ANY time you need a lifespan in PFlow including: FumeFX, AfterBurn, Krakatoa, Frost, Realflow, ect.
