I need help script flipped x-pose like a Blender


#1

I need help script flipped x-pose like a Blender.
Here is a short video on how this function works in Blender.


It is noteworthy that 10 years ago I worked in Cinema 4d and this function did not exist then. Now there is a need to make an animation project in Cinema 4d, but unfortunately the situation has not changed since then.
I would be very grateful for help in creating such a script.
All health and blessings.
