N.B.:
This is just a WIP (and a huge wall of text).
I hope to reformat it to a more readable format as well as adding a few pictures later, but I needed a first preview.
SO if you're interested in this, bookmark it and check back from time to time.

Part #1: PREPARATIONS

Spawn a new folder somewhere in your "Figures" library. This is just for easier handling the .cr2 files later on, without having to juggle with several different directories.

Open a new scene

First load your OLD character (the one you want to copy) and check which CUSTOM morphs you need to copy, and also which body parts are affected. Write it down.

Also check if there are any additional morph packs injected (apart from the "Base" and "Morphs++"). Make a note too.

Open the material room and save the texture to the "Materials" library, as a "Materials Collection" (.mc5)

Save your OLD figure to the newly-created folder in your "Figures" library.
From now on, this is your SOURCE figure!


Open a new scene again.

Load and configure SASHA (or use any of your presets if present).
Make sure that the same set of morphs is included in the new preset; otherwise, inject them now.

Save the NEW preset to the same folder as your OLD (source) character.
From now on, this is your TARGET figure!



Interlude:
For fully understanding what is an actual "morph" (which changes geometry) and what is only a "Master parameter" (which contols morphs and other dials),
PLEASE read suffix #2!



Part #2: Moving the CUSTOM Morphs across


Case A: You have PoserPro 11

In PP11 you have the option to export your custom morphs as an injection .cr2 (Menu >File >Eport >Morph Injections).

Use it!
It's much easier and faster than the manual method:

- if the morph list window appears, deselect all morphs by clicking the topmost checkbox.

Now go down the list and select only the morph(s) which you want to export.
If your morph(s) have a master parameter in the BODY actor its sufficient to only select this one: the dependent morphs in the body parts will be included automatically.
in case of morphs in body parts which don't have a master parameter in the BODY actor, scroll though the list and select them individually in each body part.

Do not tick the "Export for Conforming Figure" checkbox.

Export your morph injection by a reasonable name.

---> Skip the following and continue with Part #3



Case B: You don't have PoserPro 11

You can close Poser now, or leave it open for reference.

Open your newly creatred folder in the "Figures" library, and open both your SOURCE and your TARGET figure .cr2 files
in a separate instance of:

"Dimension3D"s "Poser File Editor" (a.k.a. PFE3)

Place both program windows side-by-side, and make sure you ALWAYS KNOW which one is your TARGET window!


To copy a morph in PFE3, first make sure that you DO NOT have set PFE3 to "Insert as child" in the "Edit" menu!
The green "down&right arrow" icon in the icon bar top right should be displayed! If it's just a "down arrow", click it once to toggle the insert mode.
Also, untick "Quick edit" in the "Edit" menu for safer selections!

OK, here we go:

Look at your SOURCE file and search for the first occurrence of your first custom morph which you want to copy.
Usually this is the master parameter in the BODY actor.
Select it, and press [CTRL]+[C].
Also remember the name of the preceding master parameter (this may, but must not be, critical if the calculation order of morphs and dials makes a difference. This is particularly true for any "fix" morphs made to "fix" other morphs!).
Let's assume that the preceding parameter dial is called "Make Art!".

Go to your TARGET file and look for the "Make Art!" dial in _this_ BODY actor.
Select it, then press [CTRL]+[V].
Your parameter dial should appear beneath the "Make Art!" dial.


Now work yourself through your SOURCE file's body parts and hunt for each occurrence of your morph:

Always the same procedure:
Select the SOURCE morph, remember the preceding morph's name, press [CTRL]+[C].
Go to the TARGET file, select the exact same preceding morph dial and press [CTRL]+[V].


Do repeat the above steps for every single of your custom morphs!


If you are sure that you have them all copied, save your TARGET .cr2 and close PFE3.





Part #3: Copy your character from SOURCE TO TARGET figure:

Again, open a new scene.
Switch the viewport to "Outline"!

FIRST load your TARGET figure.
Second, load your SOURCE figure.

Make sure that both figures are zeroed and both hip and body translations/rotations/scales are all 0.000

Turn any hair, clothing and other props on the SOURCE figure INVISIBLE (because they will obstruct your view in the comparison check!)


Now here comes the action!

If you did export your custom morphs to an injection .cr2:
Inject the morphs NOW, and continue!

If you went the manual way with PFE3, your custom morphs should already be in the TARGET figure, so you can proceed to the last step:


COPY the dial settings:

1. Select the BODY of your SOURCE figure and press [CTRL]+[C]
2. Then select the BODY of your TARGET figure and press [CTRL]+[V]
3. REPEAT step 1. and 2., but this time with the HEAD actor!

Now let the camera rotate around the figure(s), or look at them with one of the orthogonal cameras (front, side, top etc.)

The outlines must be absolutely identical from any angle of view!

IF THEY ARE NOT:

There are a couple of unilateral morphs (especially in the head) which are controlled by a master parameter.

This arises a problem:
Let's take the ears (just as an example).
There is a "Master" dial for moving both ears in/out smultaneously, yet each ear can be set separately too.
So if yo do the simple "copy/paste" as written above, the dial values will ADD UP each other;
Result: the "HRH The Prince Of Wales" ears will suddenly have their protrusion doubled!

Unfortunately there's no way to counteract this in the current Poser versions.

So (in case you used some of the master dials) you need to check back and make sure you don't have a duplication of values.

Thus the "Outline" viewpost, because it makes such errors visible!


Part #3: Reloading your textures:

This one is quite straightforward:
Just load the original texture ".mc5" that you saved previously and you're set!



REM: --- MORE TO FOLLOW ---

Next time we'll talk about how to move customized hair, clothing, and other props to your new figure.

Stay tuned!






SUFFIX #1:

In Poser, each figure that is loaded into the scene gets an "identifier" in the form of ":1" (or higher).
Each additional figure has this identifier incremented by one, so Poser can differentiate between "hip:1" and "hip:2" and assign those to the correct figure (that was the problem with "crosstalk in early Poser versions)
Usually Poser does this automatically and you don't have to worry about the correct identifieres.

BUT, and this is the important part:
Each morph dependency uses this identifier too, so if you MANUALLY copy a morph dial from figure:2 to figure:1 and forget to change the identifier, then you have "crosstalk":
Turning a dial in figure:1 will control the morph in figure:2 instead.

That's why I advised you to load one character at a time, into a new scene each, and then save them back to the library.
Like this you've made sure that both figures have the same identifier: ":1"


SUFFIX #2:

A "Master dial" is a dial that contains no actual morph data, but only controls other dials.
Usually those are prefixed "valueParm " in the Poser files.
An actual morph has a prefix "targetGeom "

"Master dials" can be placed everywhere, but usually they can be found in the BODY actor because that's where Poser automatically spawns then when you create a new custom morph with the Morph Brush.

The actual "targetGeom" morphs can be in _any_ body part which is affected by the morph, which complicates the matter.
