Ikendall,

The way I did it was to load an empty V4.2, then inject everything and save this out with a PMD file. I know that some people have had trouble with PMDs but I think this is usually from when they want to import into other software. If you have V4 characters saved in pz3's then these will be unaffected by this move, loading with all the morphs you had injected at the time they were saved.
