Blender baking problem I'm following this article about texturing a model. I'm already in step 30 but when I baked my model, I get these holes between the neck and chest. What causes this?

Edit:
Even when not baking and just setting the shading to smooth, shows this odd faces (3rd picture). I think its because of how I connected the neck to the body. Any tips on how should I correct this?

Thanks.
It was because the normals of the faces got turned upside down, so backfacing was making them invisible in textured view.

All I had to do is recalculate the normals: Tab> Edit mode > A> Select all > CtrlN> Recalculate normals.
