The dependency backend accepts targets of type UnityEngine.Object and displays all objects that the targets depend on (through references), similar to Unity’s Select Dependencies option. Unlike Unity, it shows how those objects depend on each other. This way you can see the internal structure of the that set.
Find your target object in the project view and drag it into the RI window. Nodes will be created for all objects that a target depends on. Edges represent direct dependency, edge paths mean indirect dependency.
This backend is shipped with RelationsInspector.
This image shows a prefab, depending on a behaviour of type Enemy and an animator component, which itself has dependencies.
