Hello,

I've made some progress:

However, despite the end of the cylinder being inside the box, it is not
getting "blurry", just darker. It looks like povray is treating the
scattering media as a single entity, rather than a near-infinite number of
particles which it's supposed to represent. Kasuga_Kyousuke on povray irc
advised me that radiosity will not fix this scene, because of the same
reason: looking at the media as a single entity. Does anyone know of a way
to make this work?

Thanks,
Charles

PS. Intended result: candle wax with black bead embedded

PS2. adding absorption does not work; it only makes everything evenly darker
