Use Swap sides from that script collection. For example:
- Frame zero frame should be the front-facing head pose.
- The animation keyframe in the head turn's Smart Bone Action should be shaping the head to a profile (side) view.
- Copy the keyframe for the profile view to the Smart Bone Action for the opposite side turn.
- Apply Swap Sides to the art at that keyframe.
This will give you the same animation but facing the opposite direction without having to recreate the animation manually. Basically: copy/paste the keyframe, then run the script.
Note: the script can potentially produce a weird result if Bezier points are active. The point positions will be correct, but the handles may be at an incorrect angle. To fix this, just reset the points using Smooth and redraw the handles. It's a hassle but still easier than completely redrawing.
Just thinking out loud: This
might work correctly if you click on the Bezier handles to keyframe their position them before running the script. I'd have to test this idea to be sure, but let me know if it works for you.
Tip #1: Use Hayasidist's Bake2PNG script to render a frame of the profile view and flip the resulting Image layer for visual reference. This makes is easier to match vector art's opposite side drawing accurately.
Tip #2: If you don't want to deal with the potential Swap Sides error, stick with regular Moho points instead using of Bezier points. I like using Bezier points, but when they cause animation problems (typically with bone animation), I fall back to regular Moho points, which will always work predictably.
Hope this helps.
