This addon provides a direct bridge between Blender and external UV mapping applications, specifically Headus UVLayout and RizomUV. It automates the export and import process, allowing users to send a model to their chosen UV editor, perform unwrapping and packing, and automatically update the mesh's UV maps in Blender without manual file management.

The tool supports editing existing UVs or creating new ones, handles multiple UV channels simultaneously, and properly deals with modifier states before export. For RizomUV users, a dedicated ReTake operator enables fetching the most recent UV data at any point, while automatic file saving manages the synchronization process.
