This is what im trying to achieve
The scene load a 3d obj (3 & 4), then the user can add other differents objects (1&2) who are directly added inside the blue boxes (4) invisibles, and finally thats what we get (result)
tha blue boxes have the same size as the objects selected by the user, when he click on a picture that load a new 3d obj.
How to achieve that?
