is there a simple way to get a simple particle system's particle velocity? i.e., a particle in SuperSpray. Using
ParticleVelocity <particle_sys> <particle_index>
yields a very small vector. It probably needs to be multiplied by some magic scalar, but how to get that scalar? I could use ParticlePos() to derive the velocity, but I'd prefer to simply query ParticleVelocity() if possible.
