Motion Reduction

The Motion Reduction group of settings lets you reduce the amount of motion transferred between the chest, neck, head, and shoulder body parts of your Actor to the corresponding object of your character.

Use Motion Reduction if, for example, the chest, neck, head, or shoulder sensors of your Actor are poorly captured, or when the Actor’s Marker set does not provide good capture data.

Increasing the Motion Reduction percentage is similar to applying damping. For each Motion Reduction property, use the following guidelines:

At 0%, the full movement is transferred between the Actor and character. There is no motion reduction.
At 50%, half the movement is transferred resulting in damping between Actor and character. For example, setting Head Reduction to 50% results in half the character’s head movement coming from the Actor’s head. The other half of the movement is based on other objects in the character hierarchy.
At 100%, no movement is transferred, and the character’s movement is based entirely on the other objects in the hierarchy.

Chest Reduction

A reduction percentage between 0% and 100% averages the movement between the chest object and the Hips object. Chest refers to all required and optional Spine objects. This means that Chest Reduction also affects all Spine objects.

Neck Reduction

A reduction percentage between 0% and 100% averages the movement between the Neck object and the chest. When set to 100% the neck moves at a set distance from the chest, and may result in stiff, unnatural movement since no movement is transferred to the Neck object.

Head Reduction

Adjusts the percentage of reduction when transferring motion from the Actor’s head to the character’s head object.

Shoulder Reduction

A reduction percentage between 0% and 100% averages the shoulder movement between each Shoulder object and the Chest object.
