I am trying to use the copy sop to copy a curve around a circle.
I cannot use a primative circle as the secondary input because of the nature of the noise that I am applying to the curves.

I need to be able to use cumulative transformations on the curves to copy and rotate them around a pivot point, while still being able to pass back random values from my stamp inputs.

Any ideas?

if you are using Copy SOP without second input but rather setting number of copies directly you need to use $CY variable to access id of individual copies rather than $PT

but I didn't quite understand why wouldn't you be able to use second input to copy curve on circle as you can define full transform on circle points directly and therefore avoid the need for cumulative transform on copy sop
