Fume Does not respect falloffs on forces that have them?

[Rif]

it does respect fallofs .. as far as i remember.. put a spherical wind with a decay on ( is that what u mean by fallof ? ) , it should behave like when you put ur particle system affected by it..

Now their is excecive velocity Field happening in side of the grid when using spacewarps .. thats for sure.. but if you fine tune you should be able to clean it out no ? save velocitys and turn on ur decay and enable viewport velocity eddies and tweek it down till it only affect the desired area..

let me know how it goes..
