Hey. I'm aware you're not obligated to troubleshoot for me (feel no need to reply), but since you're the creator of this model, I figure you might know something about this that I don't.

In Blender, other parts of the model and materials come up correctly, but the face seems to be missing its entire lower jaw. I have a link to what shows up in the viewport.

Any ideas? It almost seems like something forgot to come along when I ported the model.
