nice :) I suggest to use not-so-contrast texutre, as it produce strong
morey (mini-waves on wall on right side of picture) or to use stronger AA
(especialy with much lower threshold, and maybe with jitter)

I'm aware of the moir�, but there is only so much I can do with AA. My
setting are aa0.01 +r6. There was a bit of discussion about it, when I
posted the previous building, and it seems, that I can get better
results by rendering at 5 times the final resolution, and do some tricks
with gaussian blur, but that will have to wait for the final images of
the complete scene.

Not on my screen it doesn't. I always admire this kind of work - so much
time and effort.
beautifully done.

If I recollect right, these are real buildings? If it is so, the ignore this
remark, but otherwise I would like to note that the window above the left
door seems to be placed higher than the other windows which looks odd to me.

try rendering simple checker plane scene, with camera observing the
horizont and with small checker scale. It is example of almost impossible
to get rid of alias.
In this case You can use:
threshold 0.00001 method 2 depth 5..7
or typical AA, but render scene at x5 higher resolution and then down-
sample, but it would in fact be same as threshold 0.00001

pow(x-U,2)+pow(y-V,2))*.3)),2)+.9)#end#macro p(c)#if(c>1)#local l=mod(c,100
);g(2*div(l,10)-8,2*mod(l,10)-8)*p(div(c,100))#else 1#end#end light_source{
y 2}sphere{z*20 9pigment{function{p(26252423)*p(36455644)*p(66656463)}}}//M

I usually blow image at twice resolution and shrink it back both with
interpolation

They are real buildings (if I had designed them myself, there would be
much more standardization, and not eg 26 different windows), so if you
are unhappy with the design, you have to take it up with the architect.
As the building is from 1904, he may be difficult to reach... :)
Photo attached to prove that it really looks like that.

So I just have to get Rafal to get a screen like yours, and the problem
is solved :)

I don't think the threshold has much influence, it is method 2 depth 5
that is equal to rendering at 5x and reducing. If I understand it right,
threshold only determines whether two neighbouring pixels are different
enough to need antialiasing. Antialiasing pixels that are almost
identical can't do much difference in the image IMNSHO.

Thank you for your effort, but I am perfectly aware what you mean, it is
just that I don't intend to do anything about it, until the final
renderings of the comleted scene. I still need to model streets and
sidewalks, put in a dozen trees, maybe a couple of cars, some
pedestrians - I'll get back to you in a couple of years :)

Very impressive.
The only thing to complain a little: the windows do look
so, hum, dead? Maybe some image maps or only some
colored blocks behind some of the windows (not too much
and not too visible) just enough to create the impression
of life behind the walls?
Just a thought

With our patience builded with POV renderings we can wait :-)

In the final scene the windows will be reflective glass, so you can see
a nice mirror image of opposite building, but without anything to
reflect, my glass texture doesn't look good, so I have temporarily
replaced it with black.
