Yeah exactly, you need the orange but it will look more orange if there's a 
second light that's at the other end of the spectrum and in a different part 
of the scene, lots of nice contrast and varying tone.

The yellow light source inside the flame already has face_distance set. 
(And face_power=2.)

Now, here's a question. Should I add a blue *light source*, or just make 
the roof of the box bright blue and let radiosity do the rest?

Thanks. I'll give 'em a whirl.

Um... isn't that defined as cheating?

Ah well... we'll see what I can get done over the weekend...

What's the fade_distance, what's the colour and how big is the scene?

personally, I'd say scrap the radiosity, but that's because I've never had
much luck with it.
Give it a try both with and without if you have the time.

No, why would it? It's called not reinventing the wheel when it's not
necessary.

Irtc doesn't say that you must create everything yourself, just that you
must give credit for other's work
Do you not use any of the standard pov includes?

*checks*

face_distance is 50 cm. (For reference, the candle is 20 cm tall.)

Colour is <0.9, 0.8, 0.5>.

Without the radiosity, almost the entire floor is in shaddow and comes 
out pure black. (It's shaded by the candle. BTW, *real* candles do this 
also. I have *lots* of candles. What can I say? I enjoy burning things. 
Erm...)

Of course, if I add another light source...

I used functions.inc so I could access f_bozo [which is what generates 
that bizzare candle] and f_crackle [for the ice crystals]. But no, I 
never use anything else.

Personally I always use radiosity if it doesn't make my renders too slow 
(which it usually does!), particularly if I have an enclosed scene like this 
where you'd need a lot of lights to fake all the light that should be 
bouncing off the walls. I normally use the Radiosity_Fast setting in 
rad_def.inc, because it's way too complex to figure out what all the 
radiosity settings do.
