What is the key requirement for selecting artwork across multiple panels?

Selecting artwork across multiple panels in Storyboard Pro is primarily facilitated by ensuring that the layers have the same name. When layers share identical names, it allows the software to recognize and unify the artwork across those layers, making it easier to manipulate and manage content as a cohesive unit. This approach enables artists and storyboarders to work efficiently, especially when they need to apply changes or effects to specific elements that are repeated across different panels.

By having the same layer names, users can perform actions like copy-pasting, grouping, or adjusting properties uniformly across different panels without the risk of missing components. This requirement fosters consistency and streamlines workflows in projects that involve complex narratives split over multiple frames or panels.
