Short description of error
Disabling X-Axis Mirror while using Auto IK can cause a mirrored bone chain to become "locked" and not movable with Auto IK.
The "locked" bone will be highlighted in orange both when trying to move a child bone in the chain as well as moving a bone on the mirrored chain.
Seems to be the same issue as #75810, even down to the same steps to reproduce
Exact steps for others to reproduce the error
Open the attached blend and enter pose mode, then:
Arm.L
boneArm.L
bone slightlyArm.R.002
bone and move itResult: bone chain is locked in place
Hello, I can't reproduce the lock.
Try this file, where the bone has already been locked
Moving the
Arm.R.002
bone should not be possibleI can repro. You have to move the base bone of the chain to cause the lock, as demoed in the video. Moving the child doesn't cause the lock.
