Hi Folks,
    I'd be grateful for some verification of a bug I think I've found.

    Briefly, I've found that if you put a (point) light_source inside an
object holding (scattering or absorption) media they do not interact, ie
there is no lighting on a scattering media from that light_source and
neither absorption nor scattering media cast a shadow from that
light_source.

    I've attached a PoV file which shows the effect and a small image
file produced from it - the radiosity settings are simply used to show
up the edges of the boxes around the media and do not affect the effect
I have observed. The effect is most easily seen in the lack a a shadow
around the base of the right hand box.

    If other people out there can reproduce the effect, and agree that
it is a bug, I'll try putting together a bug report to meet the
PoV-Team's stringent requirements ;-)

        Hoping I'm not making a total fool of myself,
            Mike Andrews.

It is a bug (and has been fixed already). However, please note that there are users
with slow (and expensive) internet connections. So please post images in the binary
sections next time. Thanks!

Ups, ignore my other message, with radiosity on it is there...(however, radiosity is a
"experimental feature").
