unity_component_set_reference
Set an object reference on a Unity component property. Wire references between GameObjects, components, and assets using asset paths, scene names, component types, or instance IDs.
Instructions
Set an object reference on a component property. Dedicated tool for wiring references between GameObjects, components, and assets. More powerful than set_property for ObjectReference fields — supports resolution by asset path, scene GameObject name, component type, or instance ID.
