wondering if this could be done want to add an exsiting animation to another bone for example left leg moves would like to add exact animation to right leg hope that makes sense.
Single bones: Select bone, copy keys in dope sheet, then paste onto other bone (if not animated yet, fist set keys in order to get a channel).
The animation of whole bone chains of different Armatures you can transfer via actions (dopesheet->action editor / NLA editor). Make sure the bones have the same names, otherwise applying the action won’t work.
Forgot to mention that you can copy / paste (also paste mirrored) poses of bones via the 3D header buttons to the far right. After pasting a pose, insert a keyframe for it (press I)
thanks alot it worked.
