Jiggle Physics v4.5.1 for Blender
Blender 4.2 - 5.0
  • The Jiggle Physics extension for Blender is a high-performance animation tool designed to add realistic secondary motion—such as bounces, wobbles, and sways—to character rigs and objects without the need for manual keyframing. A direct fork of the popular "Wiggle 2" add-on, this extension leverages a robust Verlet-based solver to ensure that simulations remain stable and performant even under extreme motion. It is an essential utility for animators looking to add life to hair, tails, loose clothing, or soft body parts with minimal setup time.


  • One of the standout features of Jiggle Physics is its integration into the Blender viewport. Unlike traditional physics simulations that require a complex bake-and-check cycle, Jiggle Physics is designed to work at runtime. This allows artists to tweak parameters like stiffness, damping, and gravity while the animation is playing, providing immediate visual feedback. The solver is specifically optimized to prevent "explosions" or erratic behavior, making it reliable for fast-paced action scenes. Furthermore, it supports bone squash and stretch, allowing for more stylized or cartoony effects that traditional rigid simulations struggle to replicate.
  • The user interface is conveniently located in the Animation tab of the Sidebar (N-panel). Users can enable jiggle on a per-bone basis, granting granular control over which parts of a rig react to physics. The extension also includes a visual overlay system that displays the "rest pose" in green and the current simulation in red, which is invaluable for troubleshooting and fine-tuning the range of motion. For more complex interactions, it offers collision support using scaled Empties or meshes, ensuring that dangling elements don't clip through the character's body.
  • Because Blender renders frames out of order by design, Jiggle Physics includes a dedicated "Bake" functionality. This process converts the real-time simulation into standard keyframes, making the project safe for render farms and ensuring consistent results across different hardware. Whether you are working on a professional cinematic or a personal hobby project, the Jiggle Physics extension provides a streamlined, user-friendly alternative to Blender's native soft-body or cloth simulations, significantly reducing the technical overhead of character animation.
