I have added an edge bevel weight on my mesh, So I wouldn't have to add more geometry and keep the mesh as clean as possible. Once I add a MatCap material on it, the corners are visible of some unclean mesh which is visible. If I add loop cuts it will clean up the topology, but it would also distort the object. So I'd like to know how to eliminate the unclean corners without adding more geometry to the mesh.
There is also an option of using the bevel node. Manual
