Root bind but lower joints not binded
My human model is made of individual polygons.
When I proceed to binding, I selected all the polygons and then the root joint, then selected smooth binding.
When I select the root joint, the polygons are selected and can be moved.
But when I select any joints in a lower hierarchy, the polygons are not highlight, indicating that they won't move, which is true enough.
What am I missing here?
I'm using Maya7 on WinXP.
I've attached the file below.
