Hi, I have problem with editing objects. I click on the object (for example lamp) which is already placed on the world and click add object. Then I click on the bar and set child object and on the bar I see path to sub-obj.

But what to do when I want to add sub-obj to more than one object (lamps) and all of them are from one base object? I choose again one of this objects, then I click Base, then add object. Now when I set sub-obj I don't know how save obj file with added sub-obj.

Put main object in the world, click it, add sub-object, click the main object on the world again and save it.
