Particles Disappear when used as Smoke Driver -

I have successfully gotten particles to make smoke streams just as I like, but I cannot figure out how to make the particles render too (?)
This is using Cycles.

OK, I got them working , but am honestly not sure what I did different besides baking the particles first, then baking the smoke sim. Is this likely what made them visible, now?

Yes, Particles may disappear at render if they have not been baked.
