Genesis 9: Import Custom Morphs fails when "Transfer to Face Meshes" is selected

[Danny McGee]

Repro:

1. In Daz Studio, add a base Genesis 9 figure to the scene
2. Save the file
3. Run the “Export to Blender” script
4. In Blender, use DAZ Importer to import the exported file
5. Under Setup/Morphs, select “Import Custom Morphs”
6. Navigate to data/Daz 3D/Genesis 9/Base/Morphs/Daz 3D/Base Feminine 9 and select BaseFeminine_head_bs_Head.dsf
7. In the import options, select “Use Rig Property Drivers”, “Use Adjusters”, “Body part: Face”, and “Transfer to Face Meshes”
8. Press “Import Custom Morphs”

AddOn raises an exception:

After the operation completes, the new morph appears in the list and mostly works, but the tearline mesh doesn’t conform to the morph. The eyelashes mesh does seem to behave as expected.

EDIT: On further inspection, the eyes also don’t conform to the morph, which is a bigger problem. I can live without the tearline, but I’d definitely like the eyes to remain in their sockets. 🙂

For what it’s worth, I was able to fix the issue locally by updating morphing.py line 783 to this:

scale = (self.projectionFactor[char] * ob.DazScale
         if char in self.projectionFactor
         else ob.DazScale)

I have no idea if that’s correct, but the custom morph seems to work correctly after the change.

I can’t reproduce the issue. It seems you’re using a old version, please update to the last commit before reporting bugs. For eyes to work you have to enable erc morphs.

update.

The error doesn’t arise and the head morphs fine, but the eyes seem to not conform even with morph armature. I never use morph armature myself though so this may be some error on my side, better wait for Thomas to check.

‌

update. daz favorites works fine.

Using daz favorites instead of custom morphs works fine. You probably have to load some custom morphs on the eyes too that daz favorites does automatically. The thing is, custom morphs is very technical and not easy to use, it leaves maximum control to the user but you have to know what you’re doing.

I’d advise to use daz favorites instead whenever possible.

The eyes problem is that the shapekey wasn’t transferred to the eyes, only to the other face meshes. The plugin uses some heuristics to determine whether a mesh is a face mesh, which includes the mesh name and if the mesh has a “head” vertex group. That heuristics has been improved so the G9 eyes are included. However, it doesn’t cover every case so you may have to do some manual transfer afterwards.

Shapekeys aren’t automatically transferred to hair meshes, but they are to the hair cap. Hair meshes can be very heavy, and if you convert the hair to particles or hair curves the shapekeys are not needed.

Commit fbd0f25 works fine thank you for the fix. If there’s nothing to add we can close as resolved.
