yeah
so normally I will set my density to the highest fidelity I need, and unless there is some insanely detailed velocity requirement will up the Vel scale
@hanhanxue VDB point advect will still suffer from not being able to 100% push them into the smaller eddies, so I think it’s best to just own it all in the pyro sim. I took Matt’s file and just added these vortex nodes. It’s a bit heavy handed here, but vortex confinement and vortex boost along with nice substeps will give you control to make these swirls. You can click the initialize option on the SOP pyro to drop down a volumes sharpen setup. This will sharpen density _just_ a bit more, saving you some precious sim time.
