I'm having troubles with the x-axis mirror operation. Maybe because I moved the bones when the option was disabled and I shouldn't do it. But now,with the option enabled,the left and right bones are no longer symmetrical. I tried to delete the right bones and then I duplicated/flipped name/mirrored on the x or local axis the left bones,but it didn't work. They are again not symmetrical. What I should to do ? Check the attached video for a better understanding of the problem. Very thanks.
X axis mirror is mirroring along X axis considering the origin point of the object (mesh or armature) is the center of the mirror:
As your armature seems to be centered around the world center, you can
- Snap the 3D cursor to the center ShiftS then cursor to center
- Then transform the origin point of your armature using the menu in object mode: object/transform/origin to 3D cursor
If the world center was not the center of your armature, you can use other snapping options to place it where needed.
