What is the key benefit of using rigging in animation?

Using rigging in animation primarily simplifies the animation process. Rigging involves creating a skeletal structure for a character or object, which allows animators to manipulate and move these structures efficiently. By providing a framework, rigging enables animators to control various aspects of a character’s movement, such as posing and deformation, without needing to redraw or create each frame from scratch. This process saves time and effort, making it easier to produce fluid, realistic movements.

The other options do not capture the essence of rigging effectively. Creating more complex static images pertains more to illustration techniques rather than animation itself. Enhancing audio synchronization refers to aligning sound with visual elements, a different aspect of multimedia production. Lastly, replacing character models speaks to altering the visual aspects of animation rather than streamlining the animation workflow through simplified movement controls. Thus, the primary focus of rigging is on enhancing the animation process, making it not just easier but also more efficient for animators.
