Spine Links 1,2,3,4
Bend Side and Spin are the XYZ rotations for the spine.
Posture - This is a procedural control for the bending of the 4 spine objects.
Sway - This is a procedural control for the side rotation of the 4 spine objects.
Spin - This is a procedural controlling the progressive spinning of the 4 spine objects.
'P' - Progressive Mode ( the 'P' button is ON)
Posture - the spine objects will bend in a way as to make the torso breath in or out, or be proud or slouching.
Sway - the spine objects will side rotate in a way as to make the torso sway its Hips and rebalance the Spine.
'P' - Linear Mode ( the 'P' button is OFF)
Posture - the spine objects will all bend the same value forward and back
Sway - the spine objects will side rotate same value without rebalancing the spine.
'H' - this button (Hip balance) when ON, the Hips will move in local space to balance the spine and hips during Posture and Sway.
'R' and 'Recycle' - same button - Hips recycle, it's advised that you keep this button ON. If OFF, as the Hips move to rebalance the spine, you will see that center of the skeleton is now offset. The Hips Recycle function automatically converts the local position rebalancing back into real world coordinates for the Hips and removes the Local Offset.
