Sakura Poselib is a pose library add-on for Blender, created by Kafuji to replace the old pose library that was gradually phased out during the Blender 3 series. It lets you create pose data from the current armature pose, then manage those poses by categorizing and batch renaming them. Poses can be applied, combined with sliders that work the same way as Shape Keys influence values, and used directly in animations by keying pose values in the timeline.
Beyond building poses from scratch, it imports from the old pose library, mmd_tools, and PMX Editor. Pose data can be saved to a file and reused with other models. For MMD work, poses export to mmd_tools or save as CSV or VPD files, with PMX Editor listed as a supported export target. The interface lives in the Sakura tab of the 3D Viewport side panel and supports English and Japanese.
It is compatible with Blender 4.2 LTS and newer and released under the GNU General Public License v3.0 or later. If you are upgrading from an earlier add-on version, uninstall it before installing this extension.
