I think I have seen this before but now I can't find it. How can I make my
media container not throw a shadow on my fog? I thought it was a rgbt vs.
rgbf thing but that's not it...

Well, I think that's it.

sphere { y*.5, .5
	pigment { color rgbt 1 }
	interior {
		media {
			...
		}
	}
	hollow
}

fog {
	fog_type 1
	distance 200
	color rgbt<.7,.7,.7,.3>
}


Don't forget to make your container hollow...


Bouf.


P.S: tested with MegaPov, but it have to work with official Pov...

The container probably is hollow already or there wouldn't be any media showing
up anyway.  The 'transmit' for no shadowing of the media might not go for the
container itself but if it's 'rgbt 1' it shouldn't be casting a shadow to begin
with.
Perhaps it's the fog itself causing the problem, does it use a filter value?

    I'm using MegaPov and I couldn't get it to work. I am sure there must be
something else going on, but have switched from ground 'fog' to 'media' low
clouds and that seems to have fixed it while improving the overall look.

    Maybe after I get my get my IRTC render done I will look at it again.
Looks like a 10 day render as it is...

    No filter, but there is something wrong with the fog... we'll see
later...
