What is the method to connect the animation of one layer to another?

The method of connecting the animation of one layer to another is known as parenting. When you parent one layer to another, the child layer inherits the transformations and animations of the parent layer. This means that if you move, rotate, or scale the parent layer, the child layer will follow the same movements, maintaining its relative position and orientation to the parent.

This technique is extremely useful in animation as it allows for the creation of complex animations while minimizing the need for duplicate keyframes. By using parenting, animators can create hierarchical relationships between layers, making it easier to control them collectively. This is particularly beneficial in animations involving characters or objects, where certain layers (like arms, legs, or accessories) need to move in accordance with a parent layer (like the body).

In contrast, options such as linking, grouping, and layering do not provide the same level of control over animations. Linking usually refers to connecting properties or data across layers without the hierarchical relationship present in parenting. Grouping layers merely allows for the organization of layers but does not affect their animation behavior. Layering is a general term that refers to how layers are stacked in the timeline or composition, rather than how their animations are interrelated.
