Here's my quick attempt at a solution. I'll upload another version using a more practical example when I get around to it.

Here is a version using SOPs.

This is cool! Fantastic use of copernicus sdf's and the trace sop. Time to study this wrangle.

// PARAMETER
float speed = chf('speed');
//A multiplier float parameter to adjust the speed of the movement.

// UVW
int num = nuniqueval(0, 'prim', 'copynum');
// The total number of individual integer values of the copynum-attribute.

float u = i@copynum / (num - 1.0);
// Division of the copy number by the total number of copies, effectively creating a float ranging from 0.0 to 1.0 across all copies so each copy gets offset along the curve later.

v@Cd = set(u, 1.0 - u, 0.0);
// Visualization of u ranging from green to red.

// OFFSET
u = (u + @Time * speed) % 1.0;
// offsets u by the current time multiplied by speed. the modulo operator sets values above 1.0 back to its remainder. eg. 1.05 turns into 0.05

// CURVE ATTRIBUTES
vector uvw = set(u, 0.0, 0.0);
vector pos = primuv(1, 'P', 0, uvw);
vector nml = primuv(1, 'N', 0, uvw);
vector up = primuv(1, 'up', 0, uvw);
//The u float value becomes part of the vector uvw to look up position, normals, and up vectors from the curve on the second input.

// TRANSFORMATION
matrix xform = maketransform(up, nml, pos);
setpackedtransform(0, i@primnum, xform);
// Converting these three vectors into a transformation matrix that gets applied to the packed chain elements.

Really looking forward to it when you have time to upload your other version.

Here's a far better solution. I still have to clean up the file and upload it later today.

Hi. Im following this thread.

I have grabbed your zip file. If I view your am_chain node the chain vanishes. Does your am_chain.2.0.bgeo need to be copied somewhere (i'm guessing that is the issue).

Best. Mark

As promised. I've attached the needed subgraph and component you'll need for this to work, along with the hip file.
