Correct Mesh Deformations? I created a Mesh of a 3D letter &quot;P&quot;
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?

Thanks!
Polygons with more than 4 sides (ngons) do not subdivide well.

Instead of one big ngon on top like this:



try to fill your mesh with quads:



First delete the faces that have more than 4 vertices:



Add a few loop cuts (CtrlR) that match the vertices on the joints of your mesh.



Then fill the gaps making quads.



Your mesh should be nice and smooth now. Even with smooth shading or a Subdivision surface modifier.
