I'm trying to bake a normal map from a high polygon model to a low polygon one.
It's a very simple domino shape. When I use the normal on the blender render, I get this strange shape at the border of the shape
I'm not really sure what I'm doing wrong. Is the low poly shape not detailed enough? Is it too big or too small?
Here is the link to the .blend.
OK, after Mr Zak's answer I managed to understand why the baking was not creating a normal in the correct size. It was because both objects didn't have the same scale. I've applied the scale for both objects and now the normal and diffuse bake seemingly correctly.
Unfortunately, I still have the issue with the result not being as I expected
As you can see, it goes all the way to the borders now, but it has a weird shape.
For the record, this is my high poly
As you can see, the UVs are well inside the normal map, and for the diffuse it's a simple blue diffuse.
I really don't understand what I'm doing wrong with the way I bake the high poly to the low poly. could it be that my low poly is too low poly?
Here's an updated .blend.
