BoneWeaver v0.3.0 - One-click Native Linked Reorientation

BoneWeaver v0.3.0 — One-click Native Linked Reorientation

Highlights

• Added a panel-top 全自动转换并重建 L 键骨链 button that completes
  whole-Armature conversion, native hierarchy reconstruction, validation, and
  Snapshot creation in one confirmed operation.
• Added clean-room UEFormat-compatible reorientation for importer metadata,
  already-reoriented UEFormat data, and generic joint hierarchies.
• Rebuilds safe maximal linear segments with native Blender connectivity so the
  Edit Mode L key works on finger, hair, ribbon, spine, and similar chains.
• Keeps branches, Socket bones, controls, and unsafe boundaries disconnected.
• Added exact conflict-aware Restore, idempotence, automatic rollback, and
  whole-Armature/mesh invariants.

Safety and data integrity

The action may change only EditBone tail, roll, and use_connect. It does
not change heads, parents, names, weights, meshes, modifiers, animation data,
constraints, drivers, or UEFormat animation metadata. A persistent Snapshot is
written before mutation. Post-validation failure restores the original state;
manual edits after a successful conversion cause Restore to refuse the
overwrite.

Installation

Download boneweaver-0.3.0.zip, then use Edit > Preferences > Extensions >
Install from Disk in Blender 4.2 or newer. No external Python dependencies are
required.

Validation evidence

• Blender 5.2.0 LTS RC build 710df102694f.
• 220/220 Blender-hosted automated tests passed.
• Compared 154 eligible bones against UEFormat 1.0.0 at fixed commit
  8da96d65f669ca688dbf7c0141f800605a6c16e6: maximum direction error
  0.033878443821242374°, maximum length error 1.1644113720454818e-7,
  maximum Head and Socket error 0, and no parent differences.
• A raw 157-bone .uemodel completed one-click conversion, native L
  selection checks on finger/hair/ribbon/spine components, idempotent second
  execution, and exact Restore without changing its source hash.
• Existing x1.blend completed the same acceptance path under
  --factory-startup; its source hash also remained unchanged.
• The packaged extension passed isolated installation and three repeated
  unregister/register cycles.

Known limitations

• The tool changes rest-bone display orientation but does not rewrite UEFormat
  post_quat animation metadata or retarget animation bases.
• Branches intentionally delimit native linked components.
• Blender 4.2 is the manifest minimum; local executable validation used the
  Blender 5.2 build above.
