Render the following and then can someone tell me why the wall is visible
when behind the media.
#include "colors.inc"
camera {
location <-2, 0, -3>
look_at <0,1, 0>
}
light_source { <0,10, 0>
color rgb <1,1,1>}
box{ <-1,-.6,-1>, <1,9.5,1> pigment { rgbf <1,1,1,1> } hollow interior
{ media
{ emission rgb <0,.1,.2>}
}
}
difference{
box{ <-1000,9.5,-1000>, <1000,9.6,1000> pigment {Black}
}
box{ <-1,9.4,-1>, <1,10,1> pigment {Black}
}
}
box{ <0,-100,50>, <30,0,51>
pigment {rgb <1,1,1>}
}
thanks for any help.

There is no light comming from the media as your scene is now.
If you want the media to illuminate the scene, you need a radiosity scene and
turn on the media for radiosity prupose.
Add a media block in the global_settings containing at least "media on". All
radiosity parameters are optional and have default values.

Excuse me, it should have been "radiosity block" instead of "media block"
