...this time with my piano keys from an old scene. It took 11 hours
using only 2 threads on an AMD Phenom II X4 955, but the scene has a 6x6
area light, OutdoorHQ radiosity, and 49 focal blur samples... yeah, it's
slow, but it gives a really nice touch.

Wonderful and a very nice touch indeed! But excuse a question. The black keys
seems to have no SSLT. Is there a reason to it? I just took a look at my long
abandoned organ and they seem to have the same SSLT as the white but only
another colour.
Best regards,
Michael

I just thought that on a dark material it would be barely noticeable,
so I saved the render time... :) but will try it just to see how it
comes out.

A 6x6 area light? Why not a 9x9 or even 17x17 or 33x33 using adaptive 0?
In this case, adaptive 0 don't realy risk to cause any visible
artefacts, and willbe much faster while giving you smoother penumbras.
For Michael, your organ probably have plastic keys.
For most classic pianos, the white keys are ivory and the black ones are
maogany or black dyed hard wood if it's a cheap one. Whites have SSLT,
blacks don't have any, or so little that it can be ignored.

Very good indeed! Now even better would be to show the wear of the keys
and a yellowish ivory tint on the white ones: i. e. an old piano; this
one looks too new and too plastic ;-)

Looks like a typical photo from the advertising I get regularly from my
musical instruments dealer. If this is your goal it is perfect!
I for one would prefer to see an old bar piano with used ebony and ivory
keys - and the patina of hundreds of smoked cigars on it ;)
And I completely fail to see how just 11 hours is slow...

I've used always "jitter adaptive 1" for years... wouldn't "adaptive
0" shot more rays, thus being slower?

I just tested, and SSLT with an almost black pigment doesn't get much
noticeable, almost no difference at all. I guess the light would have to
be very close to the object to have an appreciable effect.

Yeah... but I was taking as reference my Korg Wavestation EX, which is
still almost new... :)

I guess that, in regards to composition, I work unconsciously with
stereotypical images...

Yes, it would make for a very nice scene... I'm already making
something very close. :)

To the contrary: It typically shoots fewer of them, four in the ideal
case. The adaptive parameter isn't a boolean that turns adaptive on, but
a numeric value governing the minimum number of rays to shoot:
0 -> 2x2
1 -> 3x3
2 -> 5x5
3 -> 9x9
4 -> 17x17
...
N -> (2^N +1)x(2^N +1)
As for the 6x6 area light, if you use the "adaptive" keyword you'll
automatically get a 9x9 area light instead.

It's amazing how I can get to use these things with decent results,
given that I understand so little of how they work... :(

Then it should be that I was not gifted with the ability to acquire
such skill...

I would make that a ":)" because hey, it indicates that POV-Ray area
lights are pretty easy to use for good result ;-)

Alain was quiet right, as ever. For a piano an organ is a bad reference due to
the plastic keys. But I think the differences between a Korg Wavestation and a
Technics SX-GN6 are smaller. But yes, the black keys shows a very smaller SSLT
than the white ones and one really should consider the efforts before modelling
it. And - as I took another road the way back home today, which leads to our
local piano dealer - the black keys on real pianos showed only a very slight
SSLT even. Fortunatelly the shop was closed and I had to look through the
display windows and not to explain a salesman why I only would like to look at
the black keys of his pianos ;-)
Best regards,
Michael

adaptive 0 start with only 4 samples, taken at the corners, while
adaptive 1 start with 9, in a 3x3 array, taken at the corners and at the
mid point between them.
6x6 don't subdivide effeciently. 5x5, 9x9, 17x17, 33x33, 65x65,... all
subdivide with the maximum effeciency.

Yes, most electronic organs do... but vintage Hammonds from the 1930s to
1960s (at least the B3 model) usually have wooden keys!

Cool, another Technics player here around! I own an SX-G5, semi-digital
from 1984 (although an SX-U90 or SX-G7 would have been my first
choice... but, beggars can't be choosers, I got it for free!).
