Ok so I created a simple animation of a nugget and in the Muscle mode I selected four splines in the middle section of the model and ran the Cloth Wizard.
What I gather is that to create the jiggly part, you'd need to model a spring cage with a "mass" particle constrained to each CP you'll want to jiggle. Then you'd have to change the spring that's connected to each "mass" particle to one of either 3 types like Structural, Fold or Shear.
Only the mass particle that's not fixed will jiggle while those that is set to Fixed will remained unaffected by the simulation (it would be surrounded along the border).
The Cloth Wizard does a great job at setting everything up automatically. But for the life of me, I can't find how to constrain the CP to the mass particle if I want to create the softbody cage manually. All that's available is a mass to bone constraint. Any idea how to add constraints to CPs?
