I have a group of items grouped to an empty. If I select the name of the empty when linking or appending, it loads it, but it does not load the associated items.
Many times, I don’t know what sub-items to load, so I’m trying to figure out how I can do this, without searhing through hundreds of items in the file dialog.
Exactly. For easy instancing you should use groups, not parent-childs. Select desired objects, Ctrl+G. This will add a group. You can change the name of this group in the F6 popup, or by going to Object tab of one of your objects and renaming it there. Having this group will allow you to instance it inside the blend (Shift+A -> Group), and easily link/append it to another file by browsing the ‘Groups’ in the blend that’s being linked/appended.
