Step-by-step explanation:
Folder hierarchy in computer animation
In computer animation, a folder that contains all of the frames of a certain character is best described as a layer palette. A layer palette is a feature in animation software that allows animators to organize and manage different elements of an animation, such as characters, backgrounds, and special effects.
Each layer palette corresponds to a specific element or character, and all the frames associated with that element or character are contained within the corresponding folder.
For example, in a 2D animated film, the animator might have a layer palette for the main character, with a folder that contains all the frames of that character's movement and expressions. This helps keep the animation project organized and allows for easier editing and manipulation of specific elements.
