With P5/P6/P7 there is now the Material Room and now the extension has changed to MT5/MT6 (MT7 ??)

MT5 is a single material that (in the material room) will apply to the currently selected material zone of the currently selected figure or prop. It was introduced in Poser 5.

MC6 is a material collection that (in the material room) will apply to the currently selected figure or prop. They are set up for a specific item or figure. They were introduced in Poser 6.

Poser 7 did not add any new file types.

Mat Pose files (pz2) have some limits. Mat Poses cannot be applied to a prop unless there is a figure in the scene and in some versions the prop must be parented to the figure. MC6 files and Mat Pz2 files that are renamed to MC6 and moved to the material library, do not suffer this restriction.
