Copy the bone color of the Active bone to all selected bones. But it cause difficulity when I need to import rig from another aprication, and generate armature to get same visual location size and local axis direction to get same FK posing by following another arpication generate rig manner. You can set joint orientations First note that bones have two representations within blender, the EditBone data represents it's static rest position within the armature while the PoseBone is the animated bone data that you would be moving around. Parse the $\begingroup$ Editing an armatures bones defines the rest pose. As you can see, the Z axis is up, when I really need it to point Blender Artists is an online creative forum that is dedicated to the growth and education of the 3D software Blender.

If you align it completely with the global X axis in Edit mode, it won't happen any more. as your bone is not completely aligned with the global X axis, rotating it on the global X axis makes it rotate on its local Z. ) When in Edit Mode you can use this panel to control position and roll of individual bones.
