Keep and rename existing groups for each copy differently?

[Krion]

Hi,

I have created a object with groups, and when I copy it, I want to be able to acces each group on each copy separately, instead of all at once on all copy.

Here I read that I could use these cool variables like $CY. Can I also use these to keep and rename existing groups?

Thank you!

Hi,

you can create an attribute on template points i.e. i@id, turn on "Use Template Point Attribute" of the Copy Stamp and you get id attribute on your geometry. Then rename groups by using that id with wrangle or wherever you like.

btw, you can get this circle primitive lines from a boolean SOP, just choose operation "Seam".

Could you maybe show me how you would do that in a Wrangle?

Is maybe a For Each method better? As I read in the documentation that they have kind of become the replacement of the Copy Stamp

I do not know much about For Each and Copy Stamping and I am going to dive into it now. I ask the example as it is something I would like to know in advance.

Thank you. Seeing stuff like this really helps me get a better understanding of Houdini.
