Karsten,

Thank you for getting back to me.

The new loopEnd node looks promising.

It was clever to use splitPt - ptExt to strip out the rotational data from the point instances.

I repurposed your wiring to do a "drunken walk" (a staple introductory exercise in computer graphics).

Nested Loops

I'm not sure how this may work with nodes. I'll see if I can build something.

Thanks again,
James
