I have a problem when I try to mirror my run animation, the IK bones on the foot go completely out of control on the mirrored portion of my animation.
The white keyframes are what I copied, and the yellow are the keyframes are the ones I pasted with (shift ctrl V)
The IK bones go completely out of control in the mirrored portion of the animation.
I used sebastian lague's amazing rigging video
After take a look into your Blender's file. I think that your problem is about your Leg Control bones aren't have the same local rotation in edit mode. So whenever you do mirror paste, your bone will move at wrong direction.
How to fix it:
P/S: You must re-animate your animation, because after reset rotation, your armature doesn't work correctly with current animation. Here is your file after i fix it. Sorry about my bad english, hope someone could edit this :(
I don't think this is just a coincidence. (I came here also from Sebastian's channel!)
The answer from Ryo is saved me, but I just want to make an update for some of like me. I use Blender 2.8 on macOS and shortcut here is Shift+n.
Also the rig in original question is not the same as in tutorial. So to make this work I had to recalculate roll for bones : Leg.L, Leg.R, Toe.L, Toe.R, LegIK.L and LegIK.R. Only after these steps it works.
