Armature with Automatic Weights ignoring mesh and overshooting

The easiest way I’ve found to get Daz models into Blender is with this addon: https://bitbucket.org/Diffeomorphic/import_daz/downloads/

You basically save your scene in Daz, go to the Daz scripts section and double click the Diffeomorphic icon, which saves your scene as a json file. In Blender, you click on the Import Daz … button and it imports the model with clothing, hair, textures, etc.
It’s a little involved to set up, not too bad, and it works like a charm.
