Instance doesn't change

[HONG KONGer]

I created a Duplicate Instance of an object, but when I scale one of them, the other one won't change, why?

Duplicate Instance of an object :

scale the the Object 's vertex ( component model )

[hehehaha]

Maya Instance does not support transform node. Please use component mode to select all the vertex than scale it up.
BTW, you can using constrain, connection editor, duplicate but using duplicate Input connection, not using Instance.
