Lightning issues with OBJ imported models

Hi All!
I have an issue with some sides of 3d object. They are dark. And it looks different in diff browsers.
All objects are loaded with OBJLoader from 3Ds Max.

Here you can see the problem:

I noticed that the scene lightning depends on object’s local pivot in 3Ds max. Also It takes effect on light positioning in three.js scene.

What am I doing wrong? Or what should I know to import obj files correctly into three.js

Thanks in advance.
