Hello, I have scattered spheres inside a tube and I want to use a noise to trigger them inflating and deflating. How would I be able to manipulate the noise to trigger the vellum sim?
Any help is appreciated.
Thanks!

After a bit more googling,I followed this tutorial [www.youtube.com] from John Lynch on the Houdini channel where he attached a null to the noise at sop level. Then he referenced it in the vellum solver using a vellum constraint property, then added some vex
float scale = fit01(rand(@primnum),0.25, 0.65);
int pt = primpoints(0, @primnum);
float amount = point(2, "amount", pt);
restscale = amount;
After following it all the points in my scene only shrinks :/ They are not even getting affected by the noise.
