How to stop emission of smoke?

Recommended Posts

Sorry, kind of new to Houdini here & surprised I can't figure this out: How do you stop smoke from being emitted within a dopnet? 

I have a scene where the smoke from an object ( a cube wired into an object merge wired into a fluid source node that creates smoke density) and then I use a suction target to make the smoke form into text when it rises. The thing is I only want the source to be emitting smoke for about 24 frames, and then I just want to watch the emitted smoke form into words. Does anyone know how I can do this?

Thanks!

Quickest way is just to animate the Activation attribute on your Source Volume node to 0 on the 25th frame or set $FF < 25 in that field
