Basic tab

Stiffness: Sets the rigidity of the jiggle, from 0 to 1. High values diminish elasticity, speed up the jiggle, and cause the points to act as if controlled by tight springs. Low values slow the jiggle and create an effect like spongy springs.
Damping: Mutes the springiness of the jiggle. A high value minimizes jiggle. A low value increases springiness.

Weight

Scales the jiggle effect up or down on all points, regardless of individual weights. The individual jiggle weights do not change value, only the overall amount of jiggle.

Jiggle Only When Object Stops: Jiggle occurs only when a moving object stops, not while it moves.
Ignore Transform: Jiggle applies only to animated points, not to the animated transform node of the object. For example, suppose you have animated a kangaroo hopping as it talks. You animated the hopping motion by keying the translate attributes of the transform node, and you animated the moving mouth by keying the points of the mouth. With Ignore Transform on, only the talking mouth jiggles.

Advanced tab

The options on the Advanced tab are common to all deformers. See Advanced deformer options.
