Wiggle 2, Wiggle Bones, Jiggle Physics and Jiggle Bake: what each Blender add-on says it does
Blender has no built-in secondary motion for bones, so people reach for an add-on. Three of them are forks in the same family (each listing says so), and a fourth, Jiggle Bake, is ours. This page puts them side by side using one rule: for the other three, we only repeat what their own extensions.blender.org listing says, as read on 2026-11-01. We have not installed or tested Wiggle 2, Wiggle Bones or Jiggle Physics, and we make no claim that Jiggle Bake is better than any of them. We publish Jiggle Bake, so read this page knowing that.
What the four are
- Wiggle 2: RTX Edition by Chamiseul. Its listing calls it a community-maintained version of the Wiggle 2 add-on by shteeve3d, updated for Blender 5.0 and 5.1. Version 2.4.0.
- Wiggle Bones by Hans_Xwh. "Refactor of Wiggle 2, fully fixed for Blender 5.0." Version 1.1.2.
- Jiggle Physics by naelstrof. A fork of Wiggle 2 with a Verlet solver. Version 4.5.3.
- Jiggle Bake, from us. Version 0.1.1.
Side by side
A dash means we could not read it in the listing. That is not the same as "the add-on cannot do it": listings are short, and an add-on may do more than its page says.
| Wiggle 2: RTX Edition | Wiggle Bones | Jiggle Physics | Jiggle Bake | |
|---|---|---|---|---|
| Where to get it | extensions.blender.org | extensions.blender.org | extensions.blender.org | Our shop page, as a zip. Not on extensions.blender.org on 2026-11-01. |
| Blender versions the listing names | 4.2 LTS and newer | 4.5 LTS and newer | 4.2 LTS and newer | 4.2 LTS and newer. Tested on 4.2.2, 4.5.15 and 5.2.3 only. |
| Licence | GPL-3.0-or-later | GPL-3.0-or-later | GPL-3.0-or-later | GPL-3.0-or-later |
| Baking | The changelog names a "Smart Bake", modal bakes and a "Bake to Disk Cache". It does not say what they write. | "A one-click bake feature converts visible wiggle bones into keyframes." | Says to "bake" jiggles before rendering. The listing does not describe how. | Bakes into a copy of your action, so the original stays as it was. |
| Settling and loops | – | Preroll, and a timeline looping option for seamless animations. | – | A settling period before frame 1, and a loop option that runs one unrecorded pass first. |
| Colliders | – | Meshes or collections, with friction, bouncing or stickiness options. | Scaled empties, and "limited support for mesh collision". No bouncing or friction. | Spheres and capsules, which can be animated. Bone tips only. |
| Stretch and squash | – | – | "Supports bone squash and stretch." | No. Rotation only. |
| Live editing | – | – | Says it lets you "tweak jiggles while your animation plays". | Live preview using the same solver as the bake. |
| FBX export | Not mentioned | Not mentioned | Not mentioned | One button with fixed settings. The result was re-imported into Blender and has not been opened in Unity, VRChat or Unreal. |
Where the listings disagree
Wiggle Bones' listing describes Wiggle 2: RTX Edition as "a complete rewrite of Wiggle 2, implementing a new physics system". The RTX Edition's own listing calls itself an optimized maintenance fork and says nothing about a rewrite. We have left that out of the table because we cannot tell which description is right.
What would make you pick one
This is the part that comes from the listings and from our own limits, not from a comparison run. If you need bones that stretch, Jiggle Physics says it supports that and Jiggle Bake does not. If you need collisions against meshes with friction or bounce, Wiggle Bones lists them and Jiggle Bake has only spheres and capsules acting on bone tips. If you want to see for yourself how the motion feels, all three of theirs are listed on extensions.blender.org with a download button, so you can try them in a few minutes.
Jiggle Bake is for a narrower job: chains of bones (hair, tails, ears, cloth strips) whose motion you need as ordinary keyframes, with an FBX export that uses fixed settings for game engines. It does not do branching, wind, cloth or soft body. If the keyframes are the point, why a live jiggle goes missing from an FBX explains why that happens and how Blender's own Bake Action helps. We tested that only with Jiggle Bake's solver.
Install Jiggle Bake from the zip: Edit › Preferences › Get Extensions › arrow menu › Install from Disk.
