You are at version 7 of an animation program and have yet to implement a simple "mirror pose" function. This is an elementary component of any decent animation package. Making a repeatable walk-cycle is twice as much work with your software!!!! Even more, if you're looking for accurate symmetry!
By "mirroring" I mean flipping a character's pose along the vertical axis (and not posing in front of a mirror). This would be done with the option of either the entire pose (whole body), or selected limbs (legs or arms).
DAZ has it Poser has it, any decent 3D software has it.
We have launched the free plugin called "Pose Manager" which can do mirror pose, please try it and give us the feedback.
And we also consider to add it into native function in the future, thanks
