I created a Mesh of a 3D letter "P" However, in order to have the open space in the middle of the Mesh I needed to have more than one face on the very top, which causes the material to look unrealistic. (I circled the deformities) So I am not sure if this is possible, but I want the mesh to have a clean top. I changed the shading to flat, which did make the top have a clean cut finish, but the siding did not have the look I was going for.
Is this possible? Here is the blender file: https://www.dropbox.com/s/ye5m8oj9p51lz7w/01.blend?dl=0
