Choice scenes are a powerful mechanism to create movies that play different scenes depending on the value of a parameter. A choice scene selects the scene to play from a pool of scenes, by testing a parameter and comparing the value to a predefined set of choices.
For example, you may have 4 movies, one for each season ("winter", "spring", "summer", "autumn") and you want to play one of them dynamically, you create a choice scene, define a parameter "season" and add 4 variants to the scene. Each variant has a "Selector" or "Condition value" that when equal to the parameter's value will enable the scene.
