How to match the surface phong shading

Hello to all why does the shade doesnt match bettween to surfaces and it always have a break in the shading

Hi @portugaldesignlab

The obvious answer is that the two surfaces are not tangent, but you need to upload your 3D file for someone to check. It might just be a render mesh issue - try setting the render mesh to smooth and slower, if ti isn’t already.
