"Is there a way to set up the animation for the node for all parts of the figure?"

If you use a Frame_number node to drive the material network you shouldn't need to keyframe anything.

Another way would be to create a version of the OBJ/CR2 file that only has one material.

A more complex way would be to edit the PZ3 to modify the shader network to use a single dial.

(Couldn't see the animation my computer doesn't seem to like DivX stuff)
