Jason Pose Manager is an alternative to Blender's default Pose Library that focuses on external file management and cross-rig functionality. Instead of binding pose assets to specific blend files, this tool packs pose data into JSON format. This allows you to export and save poses to any folder on your system, simplifying search and organization outside of Blender. Additionally, the add-on includes an inter-rig pose loading feature, allowing you to transfer saved poses between different character rigs without needing to rebuild them manually.
