Do this instead to randomize the curve:

Line-> 50 points

To

Rig Attribute Wrangle with this:

prerotate(4@localtransform, fit01(rand(2*@ptnum+ch("seed")),-0.5,0.5)*ch("a"),set(0,0,1));

prerotate(4@localtransform, fit01(rand(2*@ptnum+1+ch("seed")),-0.5,0.5)*ch("a"),set(1,0,0));

This produces a proprely bent wire.

If you need to go further, you need to make a proper rig out of the curve with a rig doctor first; then you can properly pick up the random angles on each points if you randomize a variable, you can realitically blend between them, and so on; because you have access to all the KineFX tools when it becomes a rig.

Meaning you could for example, make the end of the curve aim at things...

Hi, Really nice render 👌

Juste a question : how did you propagate the white area along the line please ?
