Wiggle 2 is a new and completely revamped version of the popular Wiggle Bones add-on (older version) for Blender.

This addon allows you to add automatic secondary animation to any bone in an armature. This results in a jiggle/wiggle effect that can be used to add motion to loose or soft meshes, such as: bellies, muscles, breasts, hair, clothing, antennas, tentacles, etc.

Wiggle 2 - Basic Usage

Getting started with Wiggle 2 is easy. Just install the addon, select and armature in the scene and you’ll find the addon settings under N-Panel > “Animation” tab > Wiggle 2.

Click on 👁Scene Muted to activate the addon in the current scene.

In Pose Mode, select the bones that you want to “wiggle” and activate Bone Tail for all of them. This makes them “wiggly” bones.

Activating Wiggle bones. All red bones are selected. Clicking on Bone Tail makes all of them “wiggle bones”

Note that the wiggly bones need to have a parent that isn’t wiggly.

You can then animate the non-wiggle parent (or any bone above it in the bone hierarchy). Secondary animation will then be automatically generated for the wiggly bones as soon as you play the animation.

Settings

The wiggle bone Settings are fairly self-explanatory.

Stiff controls the stiffness of the bones. Higher values make the bones wiggle less.
Damp (Damping) is a common setting in physics simulations. Higher values slow down the wiggle animation and make it smoother. Lower values are choppier.
Stretch: values greater than 0.0 will make the wiggle bones not just rotate but also stretch.
Gravity: higher values pull the bones down during simulation
Mass: the “weight” of each bone. It has an effect similar to Gravity. If a bone at the end of a chain has a high mass, it will pull all the other bones down.

*Wiggle Bones 2 in action. Red bones are set to wiggle. The green bone is not wiggly and it drives the animation.*

The green bone is the manually animated parent (non-wiggle). The orange ones are automatically animated “wiggle” bones.

It is possible to make the wiggle bones collide with meshes in the scene.

To finalize the bone wiggle effect, you can press the Bake Wiggle button. This will convert the secondary motion of all wiggle bones to keyframes and disable the real-time wiggle effect. After baking, the animation can be opened by anyone and it will play correctly even without the addon. This is useful for sharing your animation with others, sending the file to a render farm, or if you want to export the wiggle animation to a Game Engine or another app.

Downloads

The addon is now available on the Extensions Platform. For Blender 4.2 and later, just go to Edit > Preferences > Extensions. Search for “Wiggle 2” and install it.
