Posture is a compatibility library purely focused on allowing developers to safely manipulate the player's model. Without Posture, it's unfortunately difficult to change the pose of the player since the setup of rotations is not exposed, and model elements do no reset back to their initial position and rotations. Posture utilises Mixins in a safe and compatible manner (injections only) to introduce access into the player's model to move and rotate any limb with simple events.
