Hi all.
I'm trying to figure out how to do an apparently very easy task in a vellum sim.

Basically i would like to assign 2 different stifness in the same objebect, driven by a color.
The object should be soft and hard at the same time, but in different painted area.
i've attached a screenshot.
The red part should be hard (let's say as a wood stick) and the white one soft, as a jelly.

Any help how to solve this?

Thank you.

Vellum Constraints SOP has a dropdown next to some parameters including Stiffness, that by default says No Scaling
change it to Scale By Attribute and specify your attribute in there
