Problem when reverse copying keyframe for walk cycle Whenever I try to flip the first keyframe of my walk cycle it turns the pose into a wonky mess instead. I did some reading and figured that its something to do with bone axis alignment but i cant figure out how to fix it. Thank you in advane for the help.
Alignement is set by "Roll" property. You can access it in Edit Mode on your armature, on property panel N, for each bone.



You can also change roll on multiple bones, using Ctrl + N



In order to use correctly Mirror copying, if your Left bone has a X° roll, your right bone must have a -X° roll.
