Sorry Ken, but I'll have to disagree with you on this one as in my opinion
it is definitely a bug. The work around that I have found is to use
radiosity with the media on switch, but this is incredibly slow when the
ground is an isosurface, but this is still not a complete solution.

The media container in the example should contain clouds so I should get
some shadow from just the clouds, at the moment the whole box casts a shadow
with the above radiosity solution I still get no shadows from the clouds. I
have been experimenting with media clouds since MegaPOV and have never
experienced this problem before. I realise that POV v3.5 is not MegaPOV it's
just that MegaPOV seemed to have the correct behaviour, or maybe I was just
plain lucky and never ran into the problem, could someone please check
MegaPOV for me as I no longer have it or v3.1 installed?

Kev
