Like all your buildings, but wont sub until you add illumination map (window lights). Check the tutorials.
Also dont add flood lights inside the mesh to simulate window lights, try to keep max 2-3 flood lights per building to not fudge up framerate in a dense city. Cheers

why all your buildings don't have windows lights ?

the friend, can I ask you , as I do luegos buildings to import the game , there is a tutorial or something ?
