Noise operator?

[trenz]

You can achieve that kind of setup with a Force operator....to prevent particles from blowing away, just restore their original position at the beginning of the time step and reset the velocity each frame as well.

Hello there. I'd love to archive that but I am lost in your explication about "restore their original position at the beginning of the time step and reset the velocity each frame as well." Could you, please, explain it more in depth so we can follow all your steps?

I really need a "noise" operator or something that allow me to make a parametric "shake" effect in each particle.

Thank you so much.
