Particle Effects Fade Out

[Roy]

I am working with particle effects I am adding to a reaper mesh I am deriving.

I have the shape and particles already basically doing what I want, but when they hit the top of the sink, they just pop off and back to the bottom which is not really giving the effect I would like.

I have seen some particle effects do a sort of fade out how I want to do it, but I can not figure it out how. I spent a lot of time looking for answers and heard hints of some sort of alpha fade out. I tried messing in create mode thinking it would be similar to the killold command, but as the debug is, it has to be exact or nothing.

I do not need a total walk through or anything, but does anyone know how to do it?
