Earns its place in the Superhive library as a single-purpose converter: empties chains in, bone armatures out. It carries a 5-star rating across its reviews and more than 800 sales, and a free version on GitHub lets you try the core conversion before the paid edition's extras.
Empties To Bones is an Artell add-on for Blender that turns a hierarchy of empty objects into an armature made of bones. With one click, an animated or static empties chain becomes a proper armature, ready for tasks such as animation retargeting and animation export.
The conversion handles bone orientation automatically, generating an armature with consistent axes that is Blender armature compliant, and it includes orientation axes options. Empty shapes can be carried over as custom bone shapes, and meshes can be re-parented or skinned with vertex groups from empties to bones automatically. Animation baking is built for speed, baking thousands of frames in a few seconds.
A free version is available on GitHub, while the developer also provides support messages and ongoing maintenance and bug fixing to keep the add-on compatible with the latest Blender versions. It supports Blender 2.93 through 5.1.
Empties To Bones is best for blender users who need to convert empties hierarchies into bone armatures for animation retargeting and export.
Empties To Bones is completely free to download and use.
Empties To Bones supports Blender versions 2.93 through 5.1, covering a broad range from older builds to recent releases. The developer also notes ongoing maintenance and bug fixing intended to keep the add-on compatible with the latest Blender versions as they arrive. If you want to confirm behaviour on the exact version you're running, it's worth checking the developer's page for current details before you install.
Empties To Bones is listed as free here, and a free version is also available on the developer's GitHub. The paid edition adds automatic bone orientation with consistent axes, orientation axes options, conversion of Empty shapes to custom bone shapes, automatic re-parenting or skinning with vertex groups, and high-performance animation baking. For current licensing and what each version includes, see the developer's page.
Empties To Bones is distributed under the GPL license, according to its listing. That license governs how the add-on may be used, modified, and shared. This catalog lists the add-on as free, though a paid edition with extra features exists on the developer's site. For the full terms, any conditions that apply to your project, and current licensing details, the developer's page is the best place to review everything before you rely on it.
Empties To Bones works on both animated and static empties chains, turning either into an armature made of bones in a single click. For animated hierarchies, it includes high-performance baking that can process thousands of frames in a few seconds. The resulting armature is a proper armature with consistent axes, suited to tasks such as animation retargeting and animation export. Whether your empties are keyframed or fixed in place, the conversion produces bones ready for those downstream uses.
