That was not planed, as you surely know...

No, everyone is coming late because they know the boss is not going
to be there this morning. :)

Here in Valencia it's more typical to have panels like the ones you
describe, which a have a sort of diffuser grid instead a flat plastic
cover hiding the tubes. But of course the later was much easier to do...
anyhow, you made me try the other kind:

I tried also to decorate the ceiling panels, but radiosity didn't
like it... all sort of artifacts appeared, so I left them untextured.
I've also increased the sunlight intensity to please Christoph. :)
Thanks for the comments!

Ah... spanish offices are no more what they used to be. Now
everything is clean and people don't smoke. I've heard that now they
even work occasionally! :)

...and I thought I was finished with this one!
Many thanks for the good and detail criticism, it must be really
useful if I decide to do one more final render.

Hey now, that's so much better than seeing only blank light panels. Really
improves it.
What were your radiosity settings? Must be a way to clean up those walls.
Seems to me that recursion_limit shouldn't be too high. I like using 2 most
because of how 3 or more tends to react negatively in shadowed places. And
error_bound should be kept low (I like 0.2). Are you loading a saved
radiosity file with always_sample on to try and refine it?
Looking at POV's rad_def.inc file for an example, it has a small
pretrace_end for indoor high quality. All the choices have half of default
adc_bailout.

I'm glad you like it.

Radiosity setting were the following:
pretrace_start .05 pretrace_end .01
count 250
nearest_count 10
error_bound .5
recursion_limit 1
On the WIP 12 count was only 150. Increasing it on WIP 13 helped,
but not much. I will try your suggestions and some more things... will see.
Thanks!

Try a reduced low_error_factor (0.3 or 0.2) with a lower pretrace_end.
If that gets too slow use lower nearest_count.
Weren't you usually using a two pass method for your scenes?

Thanks for the tips... I will try them.

Yes, these were the settings for the first pass. The second pass uses
the same settings for the load, but with always_sample off and a little
increase of brightness.

It can't be... at least to my knowledge, no one ever published a
magazine called POVMAG. :)

It's on the signature: about 10 hours.

Well - then forget about low_error_factor, just use a lower error_bound
in the first pass.
