I am rebuilding some curves changing the z values of a set of their control points ( items 1 to 20 ).
than i want to replace the new set of control points with the old ones and rebuild the final curves.
I have difficulties also in changing the items z values using a graph mapper or simply a slider because I don’t understand how to get the list of items from split tree component
