Описание
Объект, назначенный полю с атрибутом SerializeReference.
Для использования, когда propertyType равен SerializedPropertyType.ManagedReference.
Объект значения должен быть типа, совместимого с базовым типом поля управляемой ссылки (то есть поля управляемой ссылки, на которое ссылается сериализованное свойство).
