I’ve manged to be able to drive a stoke sim with velocities converted from hair tangents as shown in your Splines As Distribution And Velocity Sources video. Sweet functionaily. But I’d like to use the same spline to hair to velocities from within a Pflow Stoke Field Follow. Surely this is possible? I’ve managed to assign the PRThair (with magmaModifier converting tangents to velocity) as a field node object in the stoke field follow operator, but the velocity channel doesn’t show up in the velocity dropdown in the field follow operator. What else do I have to do to make this kind of thing work?
