First save the entire morph in your Poser Character(Figures) folder (I have a folder in there named "New Characters" just for that), then you bring that character file into IPB (be prepared to wait a while) and select the V4.2+Aiko4 link under the Link Libraries over to your right. You'll want to choose INJ & REM Poses (click Selected  just below that and highlight the body and head separately. Will need to do this twice to get an INJ/REM for the head and INJ/REM for the body) and if you used any expression morphs, you'll want to uncheck "Exclude Expressions". Click on Process and once that part is complete, click on Save and place the INJ in the desired pose folder. Same for when the REM window pops up. You can also choose to rename the INJ and REM at this time. Highly suggested to rename them so that you know which is the head and which is the body. Just place a little H or B in the name either right before INJ or right after.
