What does particalEmitter.Orientation do?

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 :man_shrugging:

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
