That image with the double-boning is indeed strange and I have no idea what’s up with that…
Below I’ve listed the steps that I would use for creating a Shape based from an exported obj from DS. I don’t use Hex so I’m not familiar with the use of the Bridge so this is based on a straight obj export from DS 4.5
With Genesis morphed to your liking…
1- Set Resolution to Base and Subdivision to 0
2- Export .obj, File>Export, select type .obj, Name FBM(whatever), use Daz scale, use existing groups
3- Zero all Genesis morphs and scale or clear scene and load a new Genesis figure
4- Select Genesis and open Morph Loader Pro
5- Select Daz scale and then Choose Morph Files, navigate to the .obj and select
6- Expand the loaded morph file and Right-Click on Morphs/Morph Loader on the Property Group line and select the appropriate group from the list.
7- Right-Click on Make Unique on the Overwrite Existing line and select Deltas Only
8- Click Accept and the morph should now be created and added to Genesis
9- Find your morph in the Shaping or Parameters pane and set to 100 percent
10- With Genesis selected, open the Property Editor and select the Joint Editor Tool to view the bones.
11- In the Viewport Right-Click and select Edit>Adjust Rigging to Shape. Everything should be selected by default, click Accept and the bones should adjust to the mesh
12- Right-Click on the Property Editor Tab header or click on the menu and select Refresh Pane. Your morph should appear in the Hierarchy pane under Genesis (probably first), Right-Click on your morph and select ERC Freeze. Everything should be filled in by default (Figure and Node - Genesis, Property - your morph, Freeze Properties - all the bone positions), un-check Restore Figure Rigging and click Accept.
13- In the Shaping or Parameters pane click the gear cog for your morph and select Parameter Settings, set the Min value to 0, the Label to whatever you want to call your morph and un-check As Percent if you prefer 0 or 1 values, click Accept
14- Test your morph slider and watch that the bones follow the shape
15- Zero out your morph slider to return to the default Genesis !!This is very IMPORTANT!!
16- Select File>Save As>Support Asset>Morph Asset(s)
17- Set the Base Directory to where the data folder is located ie:My Library, enter your Vender Name (folder name) and Product Name
18- Expand the Genesis tree all the way to your morph and check your morph, un-check Compress Files if you want your files written in plain text, click Accept
19- Clear your scene and load a new Genesis, find your morph in the Shaping or Parameters pane and try it out
standard disclaimer - for personnel use only if obj is made from non-merchant resource morphs.
That said… these steps always work for me in creating new Shape morphs, but I did go ahead and test them out for what I believe you are wanting to do (exporting out a morphed figure to create a single shape morph)
Hope this helps you out…
