Ah, Ok, now I understand. The idea to have all morphs directly in the "new" cr2 came from the "original" cr2. I was in the opinion that this was everytime the same, so no revolving work.

As you have declared it makes sense to have also new "output" pz2 besides "output" cr2.

The idea to have also the possibility to have all morphs included in a cr2 should consist.
This for example is the easiest precondition for using D3D's morphing clothes. This prog need the figure morphs to copy the to the clothes. OK, it can read them via pz2 but a fully complete figure is easier to work with.

B.t.w. D3D, you should ask for help with the PMD. Could do it in german via PM.
As far as I have understood him the PMD files a only compressed morph data like otherwise given in the cr2 or pz2. The compression migth be the same as used  otherwise by poser, thatis gzip stream.
But thats acompanied by some information for the channel data. So you should ask him for this format.
