Lighting seams between objects

I have two separate objects, a face and a nose; however, as you can see from the Unity image, the lighting between the objects when rendered in Unity has seams. I'm trying to achieve seamless lighting between the objects as seen in the Blender image.

I'm at my wits end. Help would be great!

Unity (how it is looking)

Blender (how I want it to look; seamless lighting between objects)
