Help Control particles

[solidsnake9058]

Hello,

I need to pinning particles on 3d object forever in my case, just like drench honest.

How can I do for that?

I found method to control particles life when collision enter, maybe can keeps particles won't be back pool.
But I don't have any idea to pinning particles.

Or maybe I can create custom emitter by myself to create pinned particles on the object?

Thanks, and forgive my poor english.
