from the Poser 6 Reame.txt in your Poser 6 root directory: "External Binary Morph Targets ----------------------------- By default, Poser 6 saves morph targets to an external binary file format (.pmd), which contains only the morph targets for a particular figure or scene. This format allows for faster loading and greater flexibility, as the targets are no longer enmeshed with the rest of the data in the PZ3/PZZ scene file. " More explanation there. Sounds reasonable enough, but full implications haven't really sunk in yet for me. Are you guys saying it does not work for you as described? (haven't gotten that far yet here)
