Hi all,
I'm Daniele new user of Houdini, it's my first post in the community.
I searched around the forum but I found nothing, just this tutorial but I think my version it's newer

was trying to simulate a fall of noodles, I can't control the thikness of vellum hair, I referenced it to the diameter of the polywire, only that it resets every time to the default value.
Below is the scene

Many thanks in advance
Daniele

Update: I solved was a scale problem
