Jiggle deformers let you cause points on a surface or curve to shake as they move, speed up, or slow down.
The Jiggle deformer simulates the gelatinous vibrations of a gummi bear
For instance, you can create effects such as:
- a wrestler’s stomach shaking
- hair jiggling
- an insect’s antennae vibrating
You can apply jiggle to specific points or to the entire object. In the context of jiggle deformers, the term points means CVs, lattice points, or the vertices of polygonal or subdivision surfaces.
A useful technique is to apply jiggle to an influence object that underlies and alters the skin.
Be aware that you can create two or more jiggle deformers on different points of a single object. You can get the same effect more simply by applying a single jiggle deformer to the points and adjusting the jiggle weights. See Adjusting jiggle weight by painting.
