    I want to make each cable go forward in a random direction, but if I use perlin noise, it moves in a certain direction.

    I wonder how I can give different directions for each particle strip.


    This is a cable from keijiro (reference)

    And this is my cable. (All cables move in the same x direction)

    Hi @pym4742 ,

    Adding a Random Number to your sampling of the noise should give you the desired unique per-particle result:
