I know that the first two options here are all direction and y direction, but what does the remaining 2 options do?(VelocityPerpindicular and VelocityParallel)
I can’t seem to figure it out, even moving the part doesn’t do anything…
It basically makes the particles face in the way they’re going. Dont know how to explain it better 
Yeah I figured that out with a little more experimenting. The speed for my particles was set to 0 so I couldn’t figure it out
