The Jiggle plug-in by Marius Silaghi lives up to its name and is intended to make everything on animated characters or objects wobble, sway, and oscillate quickly and easily. For example, fat and muscle movements as well as skin-sliding effects are intended to be creatable without complicated muscle systems and skinning methods.
High-resolution meshes are also intended to be modifiable with the plug-in because it is multithread-capable. In addition, secondary movements are intended to be addable to an already animated character.
Jiggle is compatible with 3ds Max and 3ds Max Design from version 2008 onward and is available here for 20 dollars:
