Fix lowpoly Shading

2met7cen

Hi guys.
I have a question about shading. I need to use a low-poly model and set up shading on it in such a way as to preserve the sharp corners on the model's border, but I can't do it correctly. I tried to use the Data Transfer modifier to solve this problem, but you can see its results on the middle model. Tell me how to avoid an artifact on the upper polygons, and preserve the sharpness of the corner with the side walls.
Thanks in advance.

Use "face-weighted normals" instead of trying to transfer attributes.

However in this particular instance, it looks like you simply need hard edges.

You might consider this (last) loop cut and one edge scaling (bottom) while using smooth shading.. (?)
