P5 hides as well as P4 does. These dials are hidden until the cr2 is saved back to the library. Poser is relentless about showing morph dials (targetGeom). It takes special effort to hide them. You can make a JNTpose that will hide them on the fly, but it does not survive a CR2 save either. You have to use the pose every time. The Dial-Cleaner is supposed to rehide them, but this may be what a P5 CR2 messes up. You can make a new group in P5 and move these dials to it and then collapse it and it will be only one line. The PBMCC = partial body morph community channel. There are 30 in all groups and an additional 20 in the head. They are for authors other than DAZ to use to be slots for their morphs, without having to explain to anyone how to get slots into a cr2. Unless someone makes injection morphs that use these slots there are not going to be morphs there. There are several characters available for free that use these slots. DAZ uses the PBMDC for their additional stuff - and I think they have about used up what they added - at least for the head. By using "PBM" DAZ has used the abbreviation as a generic term for a morph. Very few head morphs of any sort are partial body, and the community morphs that use them may or may not be.
