How to modify edge smoothing normals I have two meshes that come together to form what will visibly look like one model. How can I make their smoothing appear as if the two objects were actually one?

A little background: I am trying to use the absolute lowest amount of verts I can because this model is for a game and there may be numerous instantiations of this model which will be rigged and animated.
You could remodel part of the hand so that both hand and wrist meet with 6 vertices.


And or checkout how to use Blenders Data Transfer or Normal Editor Modifiers.
I rememeber trying to get those to work when they were first added a couple of years ago but failed. Way to complicated for me.
