Visual Bone Limits is a rigging add-on that constrains bone rotations to mesh surfaces, providing a clear visual representation of the available rotation space. Designed as an alternative to Blender's native Limit Rotation constraint and IK Lock features, it allows you to define complex boundary spaces for bone movement using smooth spherical geometry. The tool is compatible with Rigify armatures, specifically supporting head, limb, and basic copy types when applied to ORG bones. Users can apply limits to multiple selected bones with a single click from the N-panel interface. You can also create custom boundary shapes by adding your own mesh templates to the add-on's dedicated collection.
