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.

I feel sorry for the people who have to live in them.

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)

Yes you are. This is very nice indeed. The logo indeed needs finetuning.

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.

Best rgds,
Holger

  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...

... set count to "256,10000" or some such (not sure whether it will make 
much of a difference though)

> error_bound 0.256

... increase the low_error factor (0.5 seems a sane value)...

... 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.
