i am new to vellum sim, In houdini17.5, i used a vellum configure strut softbody node after a rubberToy model. i only increased the both bend stiffness in cloth and stretch stiffness in struts to 10000, increased the substep to 10, and i got this result below.it feels no weight and friction.look like a balloon.
