Please help me with walking rig

Hi,

I’m working on my first rig and the animal left side walk cycle is ready. Now when Blender play the preview of animation I see the all movement, including the right side, x-Axes mirror is on. Unity plays only the left side animation.

Please help me how to copy left side movements to the right side?

PS When I try to do the same for the right side there are some little differences in movement.
Thanks in advance!

This tutorial shows the basics of Blender work cycle. Did you build it this way?

Thanks a lot! Copy -> Paste X-Flipped Pose is very useful. Tutorial is awesome!!!
