For anyone who find this because they have ZERO CLUE how to use it, here are the steps:
1. Grab the MorphMerger.cs from Github here:
https://github.com/ProjectCanyon/morph-merger/releases/tag/v1.0.7
2. Place this into your VAM's Custom\Scripts directory.
3. Load up VAM and load your character so you can see her.
4. Turn on Edit Mode, then click the "Cycle Select Person Atoms" icon. Then click Plugins from the "grape purple" colored tab area.
5. Then click Add Plugin.
6. On the submenu that appears, hit Select File...
7. In the left-side list, find the ProjectCanyon,Morph.Merger.2 option.
8. Click into src
9. Click the MorphMerger.cs
10. Then click Open Custom UI...
11. NOW you should see the god damn menu which will allow you to merge a .var file and create a .VMB/.VMI file that will later allow you to convert VAM back to DAZ Genesis 2 characters using VAM to Daz 2.2.0.exe.
12. Check box the Body and Head, name your file after your character, then hit Merge wait a minute or so then close out VAM to generate the merged files.
The plugin places the .vmb/vmi files here:
Custom\Atom\Person\Morphs\female
Hope this helps someone!
