I got this rig, initially created in lightwave and then converted to mb to play with it in Maya. In Maya it comes as a null object and one piece (single whole mesh with its joint chains). It seems I can. select the whole mesh at once but am unable to move it or scale it. As you can see from the screenshot the scale pivot point comes gray and unable to function. I cannot either scale it using the channel box. The scale X,Y,Z values come with a unit of 1 and unable to change. I can only edit the vertices and the joints skeleton.
Is there anything I can do to make it move and scale it or its nature is not for editing in Maya?
