Wiggle 2 is a ground up rewrite of the wiggle bones add-on for Blender.
- Wiggling now behaves more realistically, especially when simulating simple ropes or chains.
- Using a damped track constraint on a wiggling bone pins it to its target, with other bones responding accordingly.
- Bones can collide with a specified mesh or collection, and respond with friction, bouncing, or even stickiness.
- Wiggle 2 works properly on library linked assets, with overrides allowing you to tune your wiggle to each scene.
- One click bake converts an objects visible wiggle bones into key frames. Preroll options allow your simulation to settle. Or use it with the timeline looping option for generating seamless wiggle on animated loops.
- Everything can be managed from a single panel in the 3d animation view for streamlined, fullscreen workflows.
- Install and enable the addon.
- Enable wiggle on the scene. Found in the properties panel of the 3d viewport under the animation tab.
- Select an armature object.
- Enable wiggle on the armature.
- Select a pose bone.
- Enable wiggle on the head or tail of the bone. Note: the head will be unavailable if the bone is connected to it's parent (in which case you would just enable the parent's tail.
- Configure the bone's physics on the dropdowns for the head and tail.
- Select a collision object or collection to enable the head or tail to collide with it. This will provide further options for tuning collision behaviour.
- The global utilities offer some convenience functions like resetting physics, quickly selecting all the bones enabled for wiggling, and copying settings between bones. Note that you can always adjust individual settings on multiple selected bones at once. 'Loop physics' will prevent the physics from resetting whenever the timeline loops. 'Quality' refers to how many iterations of the constraint solver are run, which improves rope simulations.
- Bake Wiggle sub utility will convert the live physics sim into keyframes. It will operate on all visible wiggle bones in the viewport. Overwrite merges the keyframes in the armature's current action, versus creating a new one. Preroll runs the simulation for a specified number of frames, allowing the physics to settle. It also works with 'Loop physics' to help the simulation to settle into a clean animated loop.
