The other alternative is to separate and export geometry by material (I 
don't remember if Poseray allows such a think, but I know you can 
seprate things by materials in something like Wings. Then export from 
poseray w/o material, (export the rest with their original materials), 
then you have it. You can create instances of the same object, applying 
a texture to each instance.

Here is another picture.
How do you think - what needs to be changed and how to make it looks more
realistic?
- textures?
- lighting (radiosity)?
- reflection/specular settings?
- trees and grass?
- sky and clouds?

Any suggestions will be appreciated.

Yes, with ADT 2005 you can actually create many drawings from a single sheet 
through references. You start by creating a room, for instance, which is as 
simple as placing a rectangle in the drawing area. Doors and windows are 
placed with offsets, and yes the 3D work is generated on-the-fly, so no 
extrusions to be done. Further, with the content library you can apply wall 
types by actual construction material. Since the layer name and color are 
modified by content, you can imagine the power this gives you when modifying 
to POV format. Finally, section views are generated by placing the clipping 
lines, and the software generates the section, or elevation (different tools 
actually). Schedules and annotations are generated easily as well. The 
software comes with viz render and a great amount of 3D content, including 
cars, trees.furniture, and fixtures, but it's not up to the standards of POV 
artists. If you buy ADT 2005 it is built upon a foundation of AutoCAD 2005, 
so you get the core program too.

Crashes have been greatly reduced from 2002 (even in the 2004 version), but 
if you open 2002 drawings you can still have problems. I much prefer 
Inventor, but I haven't found a way to output to Pov-Ray outside of buying 
more software.

Kohler and a few other hardware manufaturers will send you free 3D content 
for your drawings just by asking.

Just visit a bookstore and check out "Mastering Autodesk Architectural 
Desktop 2004" (2005) Paul F. Aubin and autodesk press and you can see even 
more.

I have a hunch the software could second as a great level generator for FPS 
games, but I haven't tried it.

Textures would be a great start. A cobble brick, perhaps, for the parking 
spaces,  I think the blacktop would actually make a better sidewalk, and 
then come up with something darker for the lot. Brick for the red areas of 
the building, and perhaps marble or a cememtn for the gray sections.

Man, I despise flat roofs. When you render them you have to replicate the 
gravel and that can be a pain to pull off properly.

What you have here is approximately what most architecural drafters 
generate. The most recent move has been toward outside houses and more 
photo-realism. I'll go ahead and tell you that photo-realistic results can 
get you $1500/image accepted (or more depending on quality) and $135/frame 
for walkthrough animations. There can be a lot of work generated in getting 
there, so coming up with macros or programs to generate automatic output 
greatly improves upon your profit.

Good luck.

I have done some work like this as well. I had to build the modals from
scetches once. I used Lightwave at that time. In poseray you should add you
own custom code for the material pointing to a defined texture. In povray
you define that texture before each call of the object. This is very
simular to other post.

The glass on the rounded part, should that be rounded with the building?

A good sky would help as well. there are a number of them only in 360
format.

Looks good.

YOu could try using a small area light for the sun, the shadow from the tops 
of the trees looks a bit too sharp.

   Colors seem too "standard" for my taste.

   Looks a bit flat on some shadows: use higher quality settings.

   If there is some metal there, I can't recognize it. Also, the glass 
seems a bit too blue, if it isn't really a colored glass.

   I will use better POVTrees. The grass suffers from the "too standard 
green" problem.

> - sky and clouds?

   These seem good enough for the moment. Anyhow, the modeling work is 
great, and overall it is a very promising scene. And as others said, 
there is a lot of well-paid work in this field...

I think you could make a big difference by shinning your light source
through from inside a translucent object (well out of camera shot) with a
texture to emulate shadows coming from that sort of scattered cloud cover.
This would add some subtle variation to all of the colours (that currently
look a bit too uniform) throughout the scene.

You might like to try something like:

camera{location<0,14,-40>look_at 0}
light_source{<25,50,-25>rgb 1}
sphere {0,1
  pigment {granite
    color_map {
      [ 0.1  color rgbt 0.8]
      [ 0.2  color rgbt 1]
      [ 0.4  color rgbt 1]
      [ 0.5  color rgbt 0.9]
      [ 1.0  color rgbt 0.8]
    }
    scale <20,1,2>
  }
  translate <25,50,-25>
}
plane {y,0 pigment {color rgb <0,1,0>}}
box {-7,7 pigment {color rgb <1,1,1>}}

Thanks a lot to all for your advises and help. I will try all suggested
tricks and post the result of further experiments.

The parking spaces seem too narrow - looks like Door-Ding Hell.

Is there a way to macro-ize the car to get different colors?
