Using meshNode, a 3D file must have unique node name on his hirarchie

I'm using meshNode to specify one part of the 3D object.
But if there is more than one node on the 3D file with the same name, meshNode will select the first one that he find. So you have to rename all node of your 3D file with unique name.
But a 3D file can have more node with the same name if there are not on the same group.
Example of a 3D file:

---CAR
------WHEEL_1
----------Tire
----------Rim
------WHEEL_2
----------Tire
----------Rim

So we should be able to take the "tire" of the "WHHEL_2".

Actualy:
meshNode("tire") => give the first "tire" find
But:
meshNode("WHHEL_2.tire") => should be the best
