Random value from 2 trees

Hello !

I have two trees of the same length, same number of item, but differents items thanks to two jitters. I want now to make a third tree with the same length of the first two trees, but choosing randomly a branch of the first or the second tree.
For exemple :
Tree A : a1, a2, a3, a4, a5… ax.
Tree B : b1, b2, b3, b4, b5… bx.
Tree C : b1, a2, a3, b4, a5… bx.

I’m pretty sure there is something to do that. Do you have an idea ? Thanks !

If I understand you right, you can use Pick’n’Choose.

It is exactly what i needed !
I found another way to achieve it, but your’s is more simple.
if you use a “list length”, a “random” box and a “replace items” on the list A, and compare the result with the list B on a “replaces null”.
With the “random” box you can decide how much you want to replace.

Thank you a lot !
