Do any of you ever used "Use external binary morphs" with DAZ figures? What exactly is the functional difference between using delta injection poses vs. using PMD? PMD was buggy in Poser 5 but was fixed in Poser 7 and later? Is PMD only for SmithMicro figures? All I really grasp about it is that DAZ style delta injection morphs require pre-existing channels and SM figure PMD injection does not for some reason. Do they use memory resources differently? What do External Binary Morph PMD involve? What are its positives and negatives? Can some one explain all this all to me? I am not very suffisticated technically and have not understood the technical articles I have found but I would like to understand this better. Thanks.
