BoneX earns its place for relying on PhysX, a mature physics engine, to produce stable rigid body simulations with less jitter. The developer previously built a free tool based on Blender's own rigid body simulation and moved to PhysX for stable, fast results.
BoneX is a Blender addon that creates bone physics animation using PhysX, a mature physics engine used in game engines such as UE4 and Unity. It relies on PhysX to generate stable rigid body simulations, letting you add bone physics effects to character animation.
You can modify rigid body properties and set connection stiffness and damping to shape the result. Collision group masks control collision interaction, and custom collision body meshes are supported. Real-time playback interactions, partial simulation for detailed adjustments, and various constraints round out the toolset, while sub-step simulation improves accuracy on high-speed movement.
BoneX has been applied to setups like skirts, cat ears and tails, necklaces, and more, with horizontal soft connections that avoid mesh stretching. It runs on Windows and targets Blender 3.6.1 and later. The interface is available in English, Japanese, and Chinese.
Bonex - Bone Physics Animation Driven By Physx is best for character physics animation and bone physics effects in Blender, including skirts, cat ears and tails, necklaces, and similar setups.
Bonex - Bone Physics Animation Driven By Physx is completely free to download and use.
BoneX targets Blender 3.6.1 and later. On versions below 3.6.1 the addon can still be installed, but real-time simulation is not available. Goo Engine 3.6, which is based on Blender 3.6.1, can use real-time simulation. If you rely on real-time playback interactions while adjusting bone physics, staying on 3.6.1 or newer is the safe choice. For the exact setup steps and any additional notes, check the developer's page and its documentation before installing.
BoneX supports Windows. If you work on macOS or Linux, that platform is not listed among the supported options, so plan your pipeline around a Windows machine for this addon. Beyond the operating system, BoneX also depends on your Blender version, since real-time simulation requires Blender 3.6.1 or later. For the most current platform details and any changes, the developer's page is the place to confirm before you install.
BoneX ships with interface support for English, Japanese, and Chinese. That covers the addon's UI text, letting you work in whichever of the three languages suits you and making it accessible to Blender users across those language communities. If you need details on switching the interface language or on any other setup step, the developer's page and its documentation are where to look for that guidance.
BoneX includes sub-step simulation for high-speed movement. In a numerical simulation, time is split into small segments, and if that segment is too large, fast-moving rigid bodies can penetrate and produce inaccurate results. Increasing the sub-step number subdivides the simulation time further for more accuracy, though it consumes proportionally more performance, so it is best kept at one when you don't need it. This gives you a control for balancing accuracy against simulation cost on fast motion.
BoneX is listed as free in this catalog. Pricing and licensing can change over time, so for the current terms and any download details, check the developer's page on superhive. The listing includes documentation and a demo video to help you get started, and the developer, oimoyu, can be contacted directly for questions or suggestions. Confirm the latest licensing on the official page before you build it into a project.
