I appreciate the feedback. I was wondering if you could share the source of your knowledge so that I can do some further research on it? I wonder how much the .pmd files save straight up. I know that they are supposed to be used by all the iterations of a figure so that the morphs don't have to be saved in every .pz3, but if the .pmd files are smaller than the delta files, could I just save multiple Vicky 3, SP3, Aiko3 etc .cr2s and save space and get rid of the deltas at the same time? Anyway, that's something I would like to be able to research. Again thanks for the feedback.
