I was attempting to bake the AO for a pumpkin model but it end up baking the top of the model as black. I have checked that the normals are pointing the correct direction and that theres no overlapping vertices.

To assure you that the normal is correct,

How can I resolve this issue?

Possible cause n°1

Some of your top faces normals are probably pointing inward, so is taking in account the inside of the pumpking and not the outside in the face-proximity calculation.

I would firtstly try to Recalculate Normals by selecting all the faces with A while in Edit mode and then press Ctrl+N.

You can display the normal vector of each face with the option you can see in the Property panel, in the Mesh Display section.

Possible cause n°2

One of your renderable objects in the scene is partially overlapped with some faces of the object you are trying to bake. Baking process takes into account also the objects in the neighborhood.

  • I have said in the OP that i have checked the normals. To assure you of that fact, I have added the normal view. – DarkDestry Nov 11 '15 at 08:47
  • In my case, it was a hidden object at the same point overlapping at the top. Thanks. – DarkDestry Nov 11 '15 at 09:39
  • I wasn't sure at first that you already checked normals because were mentioned the UV and not the faces. Glad it helped; I'll leave both possible causes, maybe someone will find helpful the first too. – Carlo Nov 11 '15 at 10:32
