Bumped Difusse Shader Issues

I have a model that works fine with baked scene while using the built-in diffuse shader and also works fine with real-lights while using the built-in bumped diffuse shader. But If I use it with baked scene (directional) and the built-in bumped shader it revels and weird blemish. (image attached).

I guess that there’s something wrong with the model, but what?
My first bet was the normals, so I tryed to calculate instead of import it. No improvements here.

Any ideas?

As of Unity 3.5, normals are not baked so you can’t use bumped shaders. This has been fixed in Unity 4 (Unity 4: AAA graphics and performance for your mobile games | Unity Blog)

So be patient :wink: In the meantime you mean improve the result by using dual lightmapping.
