ProceduralSpineAimMatcher MonoBehaviour
Overview
The ProceduralSpineAimMatcher behaviour adapts the 3 spine bones in a player character's humanoid rig to match the aim rotation relative to the body. This means that when you aim up or down the character bends forward or back to prevent the gun and camera clipping into the body.

| Name | Type | Description |
|---|---|---|
| YawTransform | Transform | The transform to use for the body heading. |

| Aim Upper Chest | Float | The strength of the rotation to apply to the upper chest (usually this should be the strongest and all bones should add up to 1 or less). |

| Max Right Lean | Float | A target angle for the leaning bone rotation (right). The results will not be exact as the rotation is blended across the bones of the spine. |
