Bone Name Modifier is an add-on that provides a find and replace workflow for renaming bones within an active armature. It helps resolve naming mismatches that occur when merging armatures, importing rigs from various sources, or preparing models for game engines like Unity, Unreal Engine, or VRChat.

The tool operates strictly on bones, ensuring no unintended modifications to meshes. It is accessible via the N-Panel in the 3D Viewport and includes standard undo support. A fold-out help section is integrated into the user interface to explain the renaming process.
