You can save an mt5 file in the material room. That's what it was created for. Older poser versions didn't even show materials unless you were in the material room. Mt5 files were designed to be used as material files. Pz3 files were meant to be pose files. Before there was a material room, someone hacked the pose files to create mat poses, which is why mat poses are harder to make and mt5 files have a button on the library.
