adding jiggle Use the Bonus Rigging Muscle spline creator

You can use the Bonus Rigging Muscle spline creator in place of ribbon rigs if you’d like, as they also give you the option for adding jiggle simulation. You can find this under the Muscle menu>bonus Rigging>create Muscle Spline. Sometimes you will find it better to create your own ribbon rigs though, as you’ll see that you have more options available to create the layered technique, as well as better control over how the joints/ controls aim at each other (for example, the skinning of the ribbons). experiment with the options to see what it builds.
