Low poly model looks ugly with normal map

I have issue with rendering low poly model in Unity. Edges of model look ugly (side view).

In the high poly model I have smoothing at the edges. And I baked normal map via Blender but Unity does not render low poly model well in some reason.

I tried to create UV with seams on sharp corners and without its, but result is the same.
And I don’t know which way I can use to fix it.

Can this be fixed? Is it problem of baking (Blender issue)? Or maybe issue in Standard Shader? I have no idea :frowning:

Thank you for help…

You can see some screenshots below:


The issue was in the normal map.

For fixing it I started use Cage and now model looks more better.
