scene looks different in max viewport and ogre window

these are the pictures:







here is the code:
//----------------------------------------------------------------
OSMScene sm(this->smgr,Engine::GraphicManager::getInstance()->getRenderWindow());
sm.initialise("home.osm",NULL);
sm.createScene(smgr->getRootSceneNode());

//---------------------------------------------------------------------


could anyone help? thanks a lot.

Are the materials and textures needed loaded in your application, do you have any other lights created before loading the scene?

Post your Ogre.log file, it might have more hints on what your issue is
