So I have read about .mtl and .obj files and understood what you
meant. I created a program to optimize the model

But the new one that I created doesn't look the same as the old one
when I don't use texture. Please click this link to download both
versions, and use osgviewer.exe to view them.

The old one has some color (again, without texture), but the new one
doesn't. So I'm wondering what's wrong.
Quite simple: if you look at the beginning of the 'supermarket_new.obj' file you'll see
the reference to the material file: 'mtllib supermarket_new.mlt'
Note the file extension, it's 'mlt' but it should be 'mtl'.
The obj reader should complain rather loudly that it can't find this file but apparently
it isn't.
Cheers,
