Your Spectral Rendering with the updated instructions is quite simple to 
use but I need to work on lights and materials.

I posted an image of one of your favourite beasties in p.b.i. I 
decimated the mesh to speed up the rendering time. But actually it was 
the settings in the original scene that made it take so long to render. 
(It might have been the combination of light fade power, max_trace_level 
and mesh)
Anyway I need to get my head round Jamie’s Lightsys etc.

Wow. Marika Rökk, thats a surprise ;)
Note that this video is part of a documentary and those NS "Kraft durch 
Freude" scenes are not part of the movie. Personally I do not like this 
kind of editing as especially this movie cannot be considered as NS 
propaganda flick - after all it features American jazz and tap-dance!
But on the other hand she did participate in 3rd Reich propaganda movies 
and - like Leni Riefenstahl - always claimed that she was just and 
artist and did know nothing ...

Have just seen your TC entry and thought I catch you here. As usual I 
enjoyed it to follow the meanwhile familiar personal from Gancaloon but 
what immediately did catch my eye: the mud seems to be more shiny than 
the gold. In case this is not on purpose (well symbolism and such) you 
might want to do something about it ;)

Caught me. You are not wrong indeed. :-)

The problem is the gold. I finally opted to switch the finish{} off as 
the result was a white, over shiny mass, and I wanted at least the gold 
/colour/ to be visible. Even so, it is not entirely to my taste but as 
so often, I get impatient with the scene and want it over with.

One solution would probably be to get some shadow over it in order to 
block the direct sun light.

For the gold texture, I used golds_37.inc, similar to golds.inc, only 
with srgb instead of rgb.

Well, I seem to have been wrong with that too. A new test shows that the 
finish can nicely be used. It was probably in an earlier stage of scene 
building.

I shall make an update of the scene.

Thanks for pushing me :-)

Well I did enjoy jazz and blues at one time and I can listen to it occasionally.

The last scene being in colour was a bit of a giveaway. :-)

I understand you not liking it as it does hark back to those days. But for me it

clothes on. Although Jazz was banned in Germany during the NS years. I believe
that Goebbels encouraged a home grown film industry which included  German

I do sympathise in a way. It is not as if she were pitchforking babies into a
truck, just keeping up moral of the folk at home.
Anyway I cannot get that tune out of my head. I am sure that I have heard it in
English from about the same period.

How about a bit more red and a couple of small lens flares?

As far as the texture is concerned, I just took one of the golds 
available in the golds.inc. Possibly others contain more or less red. I 
think I shall keep it as is.

I am not too keen on lens flares, especially in this context. I have 
been musing about some blooming or even stars, but in the end abandoned 
the idea as a bit too artificial.

Hi all,

following Thomas' advice I have rewritten the "Spectral Rendering" page 
and hope it is now more comprehensive.
As soon as I'll find the time there is more to come ...
