(What happens when you try to inject these morph packages into M4 is that you get the morphs for the individual body part in the long unorganized list called "morph" for that part. If the morph affects more than one part, you have to make sure to apply it equally to all of them or his seams split. I could figure out all the parts affected by each morph, zero all his body morphs and spawn FBMs for each one, but that would be very tedious. )

It's not that tedious, really. At least, it's not as tedious as having to adjust the morph on each finger joint, every time you want to see what it would look like... Right? :) . You need to create a new Master Parameter for each of those partial fmbs. Load the figure, like your M4, with all the split partial fbms in it, then, using the object menu, navigate to the main "Body" channel, right click on it, and select "Create New Master Parameter." Then, follow the instructions in the manual for creating Master Parameter dials and "teaching" them what they control. For instance, you'd create the new dial, teach it that all the dials in all the groups that say "Thin" are what it is supposed to control and, once that's done, whatever value you change the dial to will be the value those other dials (partial body morphs) take on. You can also tweak the settings by having the dials take on multiples of that value. Once you get the hang of it, it's fairly easy to do and can even be a bit of fun.

There is a way to combine everything into one CR2. I've done it. I just don't remember how and don't really have much of common use for it, sorry. :( (IIRC, it's not difficult. See if you can find some old posts on the DAZ forum when Stephanie 4 was released. There was an issue getting her FMBs to load properly and the workaround I used to create a "master" V4 figure, with all possible morphs made for that particular mesh, was based on the discussions I found when people were discussing S4's initial problems on release.)
