The built-in Reference Viewer is majorly for assets references. For actors that are placed inside a level, there’s no intuitive way to see their relationships.
One method I discovered is to export the entire level as text files then search the supplied actor name and see how it’s getting referenced. It’s applicable but just really inconvenient and too indirect.
It’ll be awesome if you guys can embed this functionality in the current ReferenceViewer or create a new one because once a level gets huge those actors will be interrelated like a nest. With this, level debugging will be much easier!
