DraX, it was definately your discovery. Presented here, or Poser Technical. I quickly saw that it was way more useful than is still generally realized. I have championed it continuously since then, predominantly here. Threads here get slited over so quickly that they are impractical to use as a reference source, unless you manage to save the URL at the time. Your name for it is more ackward than I cared to deal with, and it is just a special sort of MOR pose, but as was pointed out to me, it is neither delta injection nor delta donor, it is delta replacement. Both injection and donor seem to imply (incorrectly) that an entirely new morph can be supplied using the technique, instead of altering what is there, which is what it does (even if it is the most major sort of alteration). It really was just another step in the discovery that most any variable (save a few)is open to change by using a pose file.
