Learn about the newish SerializeReference attribute in Unity, as well as the ins-and-outs of the SerializeField and Serializable attributes and how they relate to scene serialization in Unity. We'll be exploring the Unity YAML scene files as well to get a big picture view of how custom classes get serialized. Finally, we'll take a look at the package SerializeReferenceExtensions to see how we can improve our editor workflow when working with polymorphism and subclasses.
