I also tried around with the particles, but "phy delete emitter"-command looks not very nice, cause it deletes all particles immediately, no matter if they are still alive or not! That looks realy bad, for example when the whole smoke is gone from one sec. to the next! (Maybe I did something wrong, but I'm really sure everthing I did was correct!)
