Procedurally copy noise wave with different seed

Hi there,

First time post! I'm a frequent TouchDesigner user making the jump into Houdini.

My intention is to be able to copystamp a sphere along a line and link each copy's Translate X to a separate noise wave in the CHOP context (using a different seed each time).

This should be procedural, so that if I increase the number of points on the line, the noise waves will also copy and reference $PT as the seed, so that every noise is different.

I am aware of the copystamp procedure for geometry, it is the link to CHOPs that is puzzling me.

Many thanks to anyone who can help me with this (no doubt) simple task.

Cheers

hopefully helpy at min 35++

forgotten to say:

you can replace the chan{0-xxx]
with something like:
chan[0-`point("../../yourGeo/",0,"yourattr",0)`]
or
chan[0-`$NC`]



hope the comments in the file are helpy.
but if you need noise on a line, better use a vopsop or a wrangle.

compare the speed, if you do not really need chops.
yes, I know, the noise is different, but it's noise ;-)
