I’m wondering if this is actually an issue, or if it’s working how it’s meant to be. This “issue” seems to be present whenever I use PVS (PvelocitySplat)
In the scene/preview linked below I have simplified it down to a single pflow particle moving in a 45 degree straight line up and to the right through the stoke field. The velocities displayed only update every 7 or so frames. Also, I would have expected the velocities to look like lines that are heading in the same direction as the particle, rather than what they are doing. Turing on “remove divergence” makes it look a little nicer, but still only updates every 7 or so frames and doesn’t do what I would like it to. I’ve tried changing the solver timestep in PVS and also the scene FPS to see if that makes any difference, but it doesn’t seem to. Also, changing the StokeField grid size to something ridiculously small doesn’t seem to make a difference either which was my first guess.

Also, during testing I thought I’d give spray and superspray a try to see if this was related to pflow. But the “InputParticles” node in stoke field magma won’t let me pick those systems.
