The goal was to create friendly setup for turning pages by hand to the other side.
The books finally went to the game engine so all the motion needed to be baked to the joints. So I decided to founded rig on the kind of setup known as 'rivet'. So I used the bend_deformer on the page_geometry that has follicles on each vertex. The name of the game that uses this rig is Food Truck Simulator.
