Springify earns its place in the superhive library by pairing real-time spring dynamics with per-bone control, so secondary motion stays adjustable without baking or waiting on a simulation solve.
Pegaso Springify is a Blender add-on that applies spring physics to bones in real time, producing the kind of secondary motion seen in flapping wings, swaying tails, flowing hair, and loose clothing. It works without baking and without complex physics simulations, giving immediate feedback in the viewport as bones react to movement.
Each spring bone can be tuned at the bone level. You can switch between rotation-only or position plus rotation, and adjust damping, stiffness, and influence to shape everything from soft and floppy to rigid and snappy. Collider support lets you assign any mesh or bone (single or multiple) as a collider, with customizable radius, offset, and behavior, so wings don't pass through the body and tails bounce off legs. Two modes cover different stages of work: Interactive Mode listens to live movement from the rig or colliders for testing and posing, while Animation Mode responds to keyframed animation and layers physics-enhanced motion on top.
A semi-automated setup inspired by the VRM ecosystem handles the configuration behind the scenes. The add-on is lightweight and non-destructive, works with existing rigs, and has been tested from Blender 3.0 to 4.4.
Pegaso Springify (Automatic Bone Movement Without Physical Simulation) is best for riggers, animators, and game developers adding secondary motion to bird wings, animal tails and ears, character hair, clothing, and accessories on Blender rigs.
Pegaso Springify (Automatic Bone Movement Without Physical Simulation) is completely free to download and use.
Pegaso Springify has been tested from Blender 3.0 through 4.4, so it runs on Blender 4.4 alongside earlier releases in that range. This spread covers several major Blender versions, which helps when different projects sit on different builds. If you work outside that range or want to confirm behavior on your exact version, check the developer's page for the latest details before adding it to a production pipeline.
Pegaso Springify adds spring physics to bones in real time with no baking and no complex physics simulations. Bones behave like springs and react to movement automatically, with immediate feedback in the viewport. Because there is no baking step, you see results as you pose or play back animation rather than waiting on a solve. This keeps the workflow lightweight and non-destructive while still producing secondary motion on wings, tails, hair, and cloth.
Pegaso Springify includes collider support to prevent clipping and add physical interaction. You can define any mesh or bone as a collider, and it works with multiple meshes or bones at once. Collider settings are customizable, including radius, offset, and behavior, so wings don't pass through the body and tails bounce off legs. This lets spring motion stay within believable limits instead of intersecting the character or nearby geometry during movement.
Pegaso Springify offers two simulation modes for different stages of animation. Interactive Mode listens to live movement from your rig or colliders, which suits testing and posing. Animation Mode responds automatically to your keyframed animation, applying physics-enhanced motion on top of it. Switching between them lets you build and check rigs interactively, then layer spring dynamics onto finished keyframes when you polish a shot, without changing how you work between those stages.
Pegaso Springify is listed as free in this catalog. For current licensing terms and any conditions tied to using the add-on, check the developer's page, since details can change over time. On the technical side, it is lightweight, non-destructive, and compatible with existing rigs, so trying it on a current project keeps things flexible. A demo video is also available if you want to look before installing.
