If you have Poser 5 or Poser 6 you could go to the material room and create a mat file.
Just select the figure.  Then go to your library list and at the bottom you will
see Materials.  Make sure that is highlighted.
Then press the + sign below it to Add to Library.  It will give you a
pop-up menu.  If you select Material Collection and press Select Material you get
another pop up menu.  Select the parts you want the texture applied to
and hit OK. The hit OK in the first pop up menu.  And you have saved
your material collection.  Much easier than trying to hack a cr2 file
or fooling around with 3rd party software.  Basically mat poses were
just work-around left over from earlier versions of Poser and
it seems a lot of people have yet to figure out that the material
room is easier and the way to go.
