Blender Unity Shoulder Bones Stuck? The Real Reason They Dont Work

** New creators run into rigging errors when importing humanoid models into Unity, sparking fresh searches. Many assume setup mistakes, yet the truth hides in export settings and bone orientation. This fixes a classic animation blocker fast.

** Blender Unity Shoulder Bones Stuck? The Real Reason They Dont Work is misaligned parent connections and nonuniform scale. This stops proper bone inheritance and breaks IK chains in the game engine.

** During import, Unity resets transforms if bind poses mismatch Blender armatures. Studies indicate cleaner rigs when shoulder joints align with spine and elbow nodes. Keep local axes consistent across all limbs.

** A clear shoulder setup means locked rotation on local X, tight mesh weights, and correct root paths. This single habit keeps chains responsive and prevents drift during motion.

• What if shoulder bones still slide after fixing scale? Check axis conversion and re-export with NLA stripped; this often resolves hidden offset issues.
• How can I prevent future rig problems? Use standardized naming, test in pose mode, and verify bone layers before shipping builds.
