A lightmap is baked by Unity3D on machine A,
and it is imported to another machine B.
When the light is disabled, meshes in machine A is not affected by light.
But meshes in machine B is affected by light.
AFAIK, if an object is static and lightmapped, it isn’t affected by light. right?
I checked the mesh’s lihgmap index. It is set to 0.
And the mesh is static.
What should I do to fix this.
Thank you in advance.
Please anybody help me~~ 
Let me post the screenshot to understand the problem easily.
As you can see, the source is not affected by light (because the light is baked)
But when it is exported to another machine,
the light affects the environment even though the lightmap and lightmap index is set.
What is wrong?

Imported (with light)
Imported (without light)
