I used two sors (not sphere sweeps, sorry) to imitate the flame's looking and
put a light source to them. I don't know if this abstract of the scene might
show the mistake, I made. If not, I could post the full code. Again: Thank you
for your help!! :)

I am going to ask for at least the textures to this "candlelight" else their is
little to study without textures (5).

Looks like you put a lot of work into this scene and would love to see more.
Heres the flame I found, but looking at the wick it seems transparency is
missing.
The next image will be a transparent beam for study,
I dont have much trouble finding this candle flame:

oh, sorry.
Here is the pov-file with textures. If you need also the image maps, I put them
there...
http://news.povray.org/povray.binaries.misc/thread/%3Cweb.479de303cc5848d937391bc50%40news.povray.org%3E/
It would be great if someone could tell me the mistake, I made. ;)
As you saw on the pictures, without radiosity the flames were visible, with
radiosity not...
I surely made something wrong, but I can't find it. :)

As I recall media does not work properly inside objects, er something to that
effect.
The whole thing might be helpful, if the right person saw it.
also I saw "media off"
Peace,

Or was that radiosity does not work inside objects? ARGH, too few memory cells
left!

Media work inside objects with the "hollow" key word. It's the sole purpose of
that key word.

media 0 (or off) in the radiosity tells radiosity to ignore media participation:
default value.

I did not use media, did I?
