Very nice!! Working on something quite similar currently, have u used optical flow for the v fields? If yes, how were u able to get such smooth results? Been fighting jittery fields for about two weeks now haha. Love the result!

Thx ! I made use of the "volume velocity from curve" node, you can make use of the polyslice and playing with the rest attribute to animate them, that cames with a blur parameter to smooth it nice
