smoothing issue with tris sometimes when i work with tris or i change the flow of the topology on the z axe i encounter some shading issues with smooth shading, if i decrease the normal shading it gets fixed (10 degrees) but i need it higher.
i see it happening most of the times with tris even if i see some game models with tons of tris and no shading issues ( most of the times to make holes or circles.
i dont know if its a limitation of blender or something else, here an example:

topology
I solved the issue by flattening all the faces and vertices of the side i wanted and i “mark sharped“ all the border edges
