Hi everyone,

I've created BillowySmoke simulation on a polygonal sphere using the button in the pyroFX tab. I'd only like to spawn particles for a short while, but I can't figure out how to stop the simulation from spawning new particles. Does somebody know how I could do that?

In the pyro_sim, on source_density_from_sphere_object1 you can set the Activation parameter to an expression like:
$F < 24

which will emit smoke for frames less than 24 but stop emitting for 24 and greater. I'm sure some of the Houdini wizards here could offer other ways of doing this too.

Thank you! I tried it out now and it worked exactly like I wanted.
