Well you are not alone in your views. I could say that you are in the 
company of Prince Charles but I'm not that cruel. ;-)
This is a difficult subject to be objective about.
I saw many examples of attractive buildings in the link you posted. But 
then I was brought up in Glasgow, a very industrial city in my youth. I 
see beauty in lots of industrial settings. I even found the Oil Rigs I 
worked on had a strange beauty. The juxtaposition of wind farms against 
the beauty of nature is something I find attractive to look at. Even 
though I wouldn't want to live there.
I wonder, do you like the music of Bach?

I do think that most modern housing is an eyesore.

Some of those buildings were just horrible, others were better. My 
dislike of modern architecture is probably not going to stop me from 
rendering such things in the future, though. I might have already...

Yeah. There's this old cement plant nearby, totally industrial. Ugly 
stuff, though strangely captivating. A blast to explore simply for its 
nightmarish aspect (and the dizzying heights).

Somewhat.

Especially when the same design is copied over and over, in a big row :(

Excellent viewpoint, Jim! Very moody.

Attached is an example of the ceiling tiles macro (with added lights). The
design was created in Illustrator and beveled with POV. There's probably a good
scene here somewhere...

I've heard that architects are extremely busy, working long hours. I guess  
they don't have time to be creative with all these scyscrapers you need to  
be more mathematical than creative...

Lol! Ha... ah, ugh... no. I really for sorry for them :(

I love math, geometry, funny numbers. But set me to work before a large 
monolith, and everything great about it becomes nonsense after awhile. 
It's easy to forget /why/ you started something, when the end of it 
can't be seen, when the reason behind it is dust in contrast against 
what's really important.

I guess that's why I don't finish so many projects...

It is even better to be inside these buildings at night with surreal 
lighting.
Before oil rigs piped the gas ashore they flared/burned it off. The 
flickering orange light was magic. Quite hypnotic at night.

Finally got around to playing with Sams' ceiling tile macro ... I've had 
yet another change in camera pose as I was having trouble getting a good 
view of the ceiling like it was before. I'm not sure I like the emissive 
logo, but it's there as I wasn't able to tune out the radiosity 
artifacts any other way. I'm still playing around with a few things but 
I think I'm getting close.

I like that view it is nice and clean. Although I prefer the multi 
coloured conical logo. (More 3D IMO)

Ok, here my idea (very rough at the moment)

It's a robot hand. I'll work on this over the weekend. Next week, I will load up
the scene file to my blog.

Everyone than can work on this then and help to make it better and better.

  I've worked on a few thinks, but this post is about needed a bit of 
radiosity help. These are the settings I'm using:

pretrace_start 1/16
pretrace_end 1/64
count 256
error_bound 0.256
low_error_factor 0.125
nearest_count 12
gray_threshold 0
normal on

... but as you can see it's still a bit patchy. I don't think count is 
the answer and was wondering if what's needed here is in the missing 
ingredient ... min/max reuse ... right now it's default.

Any opinions?

Jim

I would reduce the pretrace_end...

much of a difference though)

... and set nearest_count to "20,10" or something alike, to make use of 
adaptive pretrace.

Recently an error has been reported in 3.70RC3 causing noticeable 
splotches when using only very few pretrace steps with a high 
pretrace_end setting; maybe that's related to what we're seeing here.

Unless you're using the current developers' version, that is. In that 
case you're already running with a fix for that error.

No I'm running the latest incantation ... initially I'd thought that was 
my problem and when it was 1st reported I pulled the fix you'd posted. 
Question about pretrace_end ... won't a smaller value make more of the 
samples to be gathered in the final pass? I thought it was better to 
shoot for having the final pass sample count about half the total. Oh 
and thanks for the nudge, I'd forgotten about the adaptive settings for 
nearest ... had been bouncing between 12 and 20 so (lol) I guess 20,12 
it is then.

No. The smaller the pretrace_end, the higher the density the pretrace 
can theoretically produce, and the fewer therefore the spots missed 
during pretrace, which need to be sampled in the final pass (i.e. the 
render proper).

(Theoretically we'd want the final pass sample count to be zero, but 
then we also want the render to finish in our lifetime.)

in addition to earlier changes I had to increase count to 384 ... it's 
not too darn bad, so I think it's worth the cycles to go to 512 for the 
beauty run. btw: I also corrected my (holy crap) spelling error in the sign.

I know you only asked about radiosity issues ;)

But I must admit I'm not too fond of the sign and the
logo here, they somehow seem to be artificial intruders in
the environment to me. I liked the earlier logo placement
better. Did you try how the scene looks with sun position
that illuminates the central column so a logo would be
visible without emissive media?

Other ideas might be to paint the logo on the floor
or on the inside of the arc to the right, maybe engrave
text on a floor slab, put up a stone sculpture, or a
mysterious pov-shaped cloud feature in the distance.

hmmm .. the engrave idea has sparked a notion so I'll try a few things, 
as I was also a bit uneasy about the current presentation ... thanks

Hey Jim,

It's looking good!

Is the water messing with the radiosity? If so--and you don't plan to have
anything reflect in the water--you might be able to use an aoi pattern with a
texture_map, using careful color settings to fake fresnel reflections.

You might also want to try the new version of OTO.inc I dropped in
p.b.scene-files. I improved the size variation of the bricks and trimmed up the
edges.

I've got radiosity importance set low on the water so I don't think I 
was the source of my radiosity problems ... since the sun is low I was 
wondering how to get it a bit of color, so maybe the aoi pattern/texture 
map idea is worth some investigation.

Cool ... I was playing around with the tile scaling then ran into a seq 
fault (see my post in beta NG) ... so it'll be interesting to see if 
your new take on OTO makes a diff.

It probably won't, and it's not my fault <g> Maybe if you use 
superellipsoids instead of rounded boxes, the memory requirement of the 
macro will be lower (just a guess).

Yep ... no difference. The number of parsed tokens sky-rockets when 
scaling is less than 0.75 (OTO). I ended up using twice that in this 
version.

I /really/ like the reflected view but I'm not so sure about the pose. 
The backside illumination on the shrubs turned out cool with the light 
at this angle, I also put some specular and a normal on the floor.

Before I decide if I want to develop this approach and further I figured 
I'd post to see what kind of reaction I get ;-)

Freakin' cool mood!

What's that bright thing in the lower right though? You didn't use 
diffuse on the reflecting plate, did you? That would be far from 
realistic for a polished surface.

the bright spot in lwr right is the light source reaching that far into 
the room, since it intercepts the reflecting plate just a little I might 
be able to transform the light source just a bit ... the texture on the 
slab is one of the copper definitions from metals.inc with a little 
emission in place of the ambient term

Emission for a metallic texture? Yuch!
The ambient terms in those texture are hugly and dirty kludges to make 
them look acceptable when there is no environment.

Metals, unless hot enough, never emit any light, they reflect it.

LOL ... ok you guys, I get the message ;-) I must've been thinking of 
something else, I checked and I have both ambient/emission set to zero 
... although setting the ambient term is moot because radiosity 
effectively sets it to zero.

How's this for a different approach ... I actually like this! It's just 
an intersection slice of the distribution logo repeated using an 
adaptation of the helix solution that Le_Forgeron posted a while ago.The 
text and "helix-logo" object are textured together so the text gets it's 
pigment from the depth position. The background uses Sam's OTO (Odd 
Tiles Object) macro. Comments appreciated.

I like both helix and colors, but the word "(P)ersistence" is difficult 
to read. Perhaps in another color wuold be better.

  well how about that! in the non area light version those letters cast 
a shadow on the object that helped with that ... i rendered the area 
light version without the preview and didn't notice that it (the area 
light) obliterated the shadow. guess my size parameters could use a 
tweak or two

Same as in virtually every Windows program. Click on the heading of the
