You'll have to add an `inside_vector` statement (unless your converter
software already does that for you).

I like the light in the night, too.

Yes, I edit the model with SketchUp to get the cutaway. POVray 's CSG difference
is not ok to cut a mesh data, I have tried many times.

So I see that it states an "inside_vector <0,0,1> "(from poseray) in the last
item in each mesh2 object. It does not contain sufficient information.

With that statement, the mesh should work fine in CSG difference (or
intersection or union, for that matter).
Not sure what you mean by "it does not contain sufficient information".

In my point of view Povray is nice to render such an image. I feel it is a good
tool. I original thought that placing a repeat object(one with syntax
"no_image") is a bad idea. I assumed it will take very long time to render. But
just... in the range that can be.
But there are some bugs in the image. Why the small wardrobe is not completely
dark, it should be black but instead it appears dark red? Because I have checked
that there is no any open or window to the outside, and the only major light
source in the scene is the sunlight and the sky_sphere light.

Maybe `ambient` is to blame?
Also, radiosity sometimes leaks light in places where it shouldn't.
Careful tuning of the parameters might help.

Because there is just one vector <0,0,1> at the end, I suppose that it should
be a lot of vectors. Maybe each face have one vector, and should vary from face
to face, I don't know。。。 I suppose it should look like
that.

No; there is only one `inside_vector` per mesh; it tells POV-Ray that in
order to test whether a given point is inside the mesh or not, it should
shoot a ray in the direction specified by that parameter, and count the
number of surfaces encountered in that direction. If the count is odd,
the point must be inside the mesh; if the count is even, the point must
be outside.
