Blender cycles normal map not generated correctly I'm really, really new to Blender and 3D in general, so I apologise in advance if this is a silly question.

I've created a high poly model, and a low poly version.  Then using Cycles, I've baked a normal map onto the low poly model, however, as the picture shows, something isn't right.



I've done some reading, but I can't quite understand what the problem is here.  If anyone could offer some advice or input, I'd greatly appreciate it.

After advice from Bithur, I've added a Ray Distance to the map, from .5 to 1 and it's still not working, it looks better, but still not right.  As this picture shows.
Add some ray distance to your baking, it will use the "inside" of your mesh.
