As title. I'd like to make my Vellum fluid kinda move more slowly in air, but not changing the gravity for other particles. I suppose it can be done by giving it some areodynamic drag.
Adding a POP Drag to give it wind seems to be close... but wind is a vector (as it should be), and I'd like an omnidirectional aerodynamic drag. Set POP Drag's air resistance without wind seems to do nothing.
