How to: Mirror Mecanim Animation about different axis

I have an animation of my character walkiing forward and I want to have a mirrored clip of it to use for walking backwards. Problem is when mirroring the clip in my blend tree I don’t get to choose the axis to mirror about. As a result my character instead of walking backwards is just holding his gun on his other shoulder.

Mirroring is a feature only supported by Humanoid Mecanim rigs, and was created to make switching between left-handed and right-handed animations easily. It only supports the left to right flip. I thought this was kind of strange myself but then I realized Mecanim neatly breaks the rig into left and right arms and legs for IK mapping, so it would make sense to mirror across that axis only. You’ll have to do your mirroring in another program and import it as a new animation. Or you can do what I did and just hand animate an actual backwards animation.
