Overrides

Properties can be overridden for each level (Campaign, Chapter, Map). For example, defining the background_image property in both the Campaign and Chapter block will set the background image to the one defined in the Chapter block if the player is currently in that chapter.

This way your campaign can have a customized interface for each chapter.
