For the headmorph: (You probably know this, but I'll post it in case someone else looking at the thread doesn't know how to create a headmorph.)
1) In Gibbed open the ME3 save containing the Shepard you want to create a headmorph for.
2) From the "Player" tab select the "Appearance" tab.
3) Click "Head Morph" to open the drop menu.
4) Select "Export To File...".
5) I recommend saving the .me3headmorph file to its own folder (Example - C:\Users\<username>\Documents\BioWare\Mass Effect 3\Headmophs).
6) Once you have a location and file name click "Save".
Creating the save:
- I've heard that you can create a save in Gibbed, but I always begin by creating a save with ME3 and then editing it in Gibbed.
- Choose the options (class, background, etc.) you would like to play as you go through the character creation process in ME3.
- Make sure you select a custom Shepard appearance and not the default one; it doesn't matter what your custom character creation Shepard looks like since the intention is to use a headmorph.
- When ready allow the game to begin the intro and wait for it to do the first autosave; once the game saves you can exit out and begin editing the save in Gibbed. (It's not necessary to wait until you have control of your character.)
Importing your headmorph:
1) Open the ME3 save in Gibbed.
2) From the "Player" tab select the "Appearance" tab.
3) Click "Head Morph" to open the drop menu.
4) Select "Import From File...".
5) Select your .me3headmorph file.
6) Click "Save".
Other recommendations:
If I don't import one of my ME2 saves I usually begin by finding a save file on Mass Effect 2 Save ( http://www.masseffect2saves.com/index.php ) that most closely resembles the Shepard I'm looking to play.
I'll usually open the ME2 save in ME2's Gibbed Save Save Editor ( http://social.bioware.com/project/4373/ ) to review plot/romance choices and to change the character's name. When I'm finished making ME2 changes I'll save the file using the data on the "Player" -> "Basic" tab to create a new folder in "C:\Users\<usenamer>\Documents\BioWare\Mass Effect 2\Save".
Folder Name Format: <Character Name>_<Character Level>_<Character Class>_<date>
Example: Marcus_33_Sentinel_010913
Then I use "New Game" --> "Import ME2 Character" for ME3.
