My render uses double_illuminate. That's the only way I got the candle to
brighten up along the sides. diffuse 0.5 and double_illuminate. no_shadow is
not right... it's supposed to cast shadows! I also used light fading...

Pretty good actually. At least you added a flame. ^_^

That's quite a compliment coming from you. Thanks! :) I might just put some
more work into it.

I use two copys of the object, one with double_illuminate and no shadow and
one with a transparent texture and light attenuation(that's what I wanted to
say with light_fading)
Render time is only a few seconds.
