I want to clone smoke and make it disipear after awhile (to not build) but I'm not sure how to make clone or pbcn do that. It seems like I can only manually add life to something and that it can't spawn in with it.

Im making cigarete smoke in a bunker and don't want to add void to remove the smoke. I'm using delay and pbcn so it isn't a constant flow of smoke (like just using clone or mort) but given enough time it still builds up.
