LW>B: "Use Bones From" equivalent?

(I’d look this stuff up myself if the Search function in the really pretty good Blender dox was more useful.)

In LW you can tell an Object to use bones from another Object. This is good for a variety of tasks when you want to maintain multiple meshes to comprise one ‘object’.

What’s the Blender equivalent?

Just use the same armature for all objects. To clearify: if you setup your main object with an armature by ctrl+p automatic weights. You do the exact same procedure for your other object and use the same armature. Easy!
