There are 2 ways to save and use your morph. The easiest (in my opinion) is to go to File/Export and near the top of the pop up select Morph Injection... This will ask for a name and a location for the injection. Then a selection box will open and you can select the morph or morphs you want to save. Once you click ok (or whatever) it will save 2 files to your location, one is a PMD file the other is a Pose file. The Pose file will used the PMD file to inject the morph(s) into a selected figure in the scene.

The 2nd way is simply to save the figure with your morphs into the Character folder of poser but be sure to use a new name or it can over right you L'Homme figure. When you open your new Poser file you can load the figure with the morphs. The big set back to this for me is that you are crowding you figure file And it will only load the figure with the morphs you save with it. By using injections to save your morphs you can add them any time you open a new figure and if you have several (or more) morphs you can now mix and match, Also in the old days using ht ePMD would save a it of disk space, not as important with the current hard drives but way back when every bit counted. Hope this help! Letterworks PS injection morph made for L'Homme CAN be injected into LaFemme they use basically the same mesh, just rearranged a bit, but I don;t guaranty the results will work exactly the same since the mesh has been re-arranged but it may give some interesting reusults.
