Hello,
There is some problem with the instances and clones:
1) When creating primitive objects (box, sphere ...) the instance is displayed. But if we create instances from mesh that we import (ImportMesh). the instance is not visible (it seems to create, but it is not rendered)
See in this PG: http://playground.babylonjs.com/#8GY6J8#117
2) Another problem, is on my project when I refresh my page and reload the scene, the instance that I created that has not been rendered, can now see each other, but it is not pickable. I can not select the instance with the gizmo. With primitive objects the instances are selectable.

3) I try with the clones and it seems to work. it is rendered. But the clone can not be selected too and moreover, it is at the wrong position with respect to that specify.
And we must select the first object that moves all the clones, which is not logical, they are not parent / children. (It works with primitive objects)
