opacity over life

[Dubber17]

Hi, I'm currently working on a smoke effect where I need the smoke to be less visible (transparent) at the beginning of its simulation, then get more opaque as it rises into the air. Right now I have it where there is way to much smoke 'billowing' at the beginning of the simulation.
for example; like in 'particular for after effects' it has an 'opacity over life' curve that I can adjust.
Does such a thing exist in FumeFX? If no, is there a 'work around' for this? If yes, I would be very grateful to learn how to accomplish this!!
Thanks in advance!

I haven't really had a chance to work with them myself yet-but I'd say check the docks on using effectors.

Hi Dubber17,

maybe I don't get you right, but can't you just animate the opacity in the smoke shader?
