Overriding Scenes and Prefabs
You can override existing scenes and prefabs by creating new one with the same name.
You should keep in mind that overriding prefabs may break existing scripts if you change entity hierarchy. Make sure you preserve entity hierarchy to avoid possible breaking errors if your entity is being used by existing scripts.
Prefabs
Prefab definitions are stored in xml files located in Prefabs folder in each module’s directory.
Scenes
Scenes are stored in two separate folders SceneObj and SceneEditData in each module’s directory. SceneObj folder stores necessary files to open scene in client mode while SceneEditData stores files necessary for editing operations.
