An elementary mystery that's beyond me: I can't figure out how to apply injection files to a Poser Victoria 4. Take face/head morphs. Having downloaded, unzipped. and planted the PZ2 files in the Poser Poses library -- what next? Was that correct so far? Clicking on the figure's head and selecting the PZ2 file doesn't do anything. Can some patient person please explain, step by step?

Thanks.
