Linker is a Blender add-on that enables live linking for external FBX and OBJ files. When a source model file is updated externally, the add-on automatically updates the corresponding object within the active Blender scene. Designed to support collaborative workflows and asset pipelines, it allows users to manage external file dependencies more efficiently.

The tool includes options to toggle synchronization, which helps manage performance when working with heavy models. Users can link or unlink individual objects to maintain unique local copies independent of the source file. It also provides a quick export function to save models as linked FBX source files directly from the Blender workspace.
