Z Size Value is random

[elfin]

Hi,
I'm creating a simple city railclone, all the walls are made of one plane segment, which gets randomized in height for buildings variability.
I tried Randomize node, exported its Z Size and used it for Array 2S Y Size.
It works quite well, walls heights match the Y Size of the Generator for every building. Variations
But that same value Z Size value doesn't work when I apply it to generate rooftops.
Please let me know if there is any solution.
Thanks!

Sync between generators fixed the problem.

Hi, would it be possible for you to share the .max file that works ?
