yeah I have a file for that somewhere. You still need to resim it from the velocity field though

not the pyro, just the rest fields.

lemme try and find it

rest field from vel field

makes it so you don’t have to resim the entire pyro just to get a change in the rest fields

yeah they just go away

cuz like there will be no zero crossing most likely

if the inset is too small, and the resolution isnt high enough ull get artifacts though

so if u want realllly thin borders ud have to crank the resolution to like 1000 frequency on the sphere

lemme save this out one sec

@Solitude @nicholas ralabate so I’ve somehow never heard of Gas Velocity Stretch before but it basically takes care of all this rotation business for you

and you can feed p@rot through a 2nd gas velocity stretch node using a different field to drive extra rotation

here’s a curl analysis piped into p@rot
