[Diffeo] Morphing Armatures not working

With the introduction of ERC in Diffeo, I am looking forward to the many possibilities.
For example, when the body or face of a figure is sculpted into a completely different shape, the bones remain undeformed, so I thought that this 'mesh-bone' mismatch could be resolved.


So, referring to the post, I did a simple test.

https://diffeomorphic.blogspot.com/2021/09/morphing-armatures.html
I checked 'ERC Morphs' in Global Settings and used the figure's base mesh.


Image 1 : Increase the XYZ scale of the figure mesh by 1.2x
Image 2: Click the 'Morph Armature' button after selecting the figure's Armature


I thought Armature would match the mesh scale, but nothing happened.
It was the same when I sculpt only the arms into a large form and then run Morph Armature.
Is Morph Armature not applicable to transform like the test above?

    From what I understand that's not how it is supposed to work. The "morph armature" tool and script need some ERCs to be imported and applied to the figure. That is, the tool follows the ERCs, it doesn't follow your own morphs you made in blender. Then I don't know if there's some blender addon that could transfer a shapekey to the armature rest pose. Usually you fit a metarig by hand.

    After importing all the morphs from the morphs folder of a custom character product as custom morphs, applying them to the base G8, and running Morph Armature, it works properly.
    It seems that the character's body and head morph contain ERC data.
    If I could sculpt a Daz figure as I wanted in Blender and then auto-match the bones through Morph Armature, it would be the ultimate feature in character modeling.
    Of course, Diffeo is already powerful enough.

    May be Thomas can write a tool to transfer a shapekey to the rest pose. I have no idea if this is difficult or doable at all. Going to ask ..

    update. We got some answers and it seems it's not gonna happen.

    I read the discussion. As expected, that would be difficult.
    As with clothes, I think that proper use of manual and automatic is better than full manual in rigging.
    As you know, through 'Adjust Rigging to Shape'.

    http://docs.daz3d.com/doku.php/public/software/dazstudio/4/userguide/creating_content/modeling/tutorials/auto_rig/start

    Anyway, thanks for asking. :D
