Static object still receiving real time light (mixed) after bake.

The red light in my scene is in mode MIXED... the whole object you can see (just) is static. The ambient lighting is also set to Baked.
After a bake most of the object works correctly but the red parts you can see are responding to a real time light in the editor. If i turn it off, they disappear, yet they are definitely static objects. I think it corresponds to those parts of the model which are shiny. Using Unity's standard shader.
I was under the impression that static objects after a light bake should not be affected by MIXED lighting ?
Any clues here?
Thanks

 

sometimes it was cause by your import settings, check your mesh import setting and make sure u got enable the lightmap support for the mesh
