I'm curious about any tips or techniques folks have used to setup Pyro to attract and follow geometry, like a character forming out of smoke. I've run some particle sims that I'm using to create velocity fields to move the smoke around, which seems to get me halfway there. Any advice is greatly appreciated

did you try Attract Fluid shelftool from Container Tools tab?

I've tried it but didn't get very directable results, I'll have to give it another look

any luck with that? Me too, I cant seem to find a proper way to direct smoke to get into clear defined shapes

I'm getting better results now with the Fluid Attract Tools once I spent some time building better SDFs from my target geometry. Like so many things in Houdini, it's all about the SDF.
