Ok, one street block finished. there are like 7 more left. These should go faster, coz now i know exactly what to do while joining ground with the buildings.
3 screenshots:

Thats CS renders. from blender of course.
Listen careful now There is that bug that most of the faces are unafected by the light (their lightness is always the same as original texture, no matter what) You can recognize these faces, because you can actually see them you-could-think-alright.
The faces without a bug are very dark. These faces are ok. If i added more lights, like street lamps, but especially ambient light... then they would look more or less ok.
If you know what is this issue, and so know how fix it. WRITE.
Someone could wonder why do i bother if it is going to be exported to max anyway. But still, i want it fixed, also to make better screenshots ;]
Also, a watchtower has been added and citygate for the uper quarter (not visible ate screenshots, because there is not much to look at yet)
