Ugh... that's one of my little contributions. That room with a window isn't
as simple as it looks. Simple to get the media looking good, I mean. Media
seldom is easy when it comes to using it under varying circumstances, as you
must know by now.

Ok. Wow, that is quite a file so I was glad to find out that the fix might
be as uncomplicated as reducing the scattering value by a factor of ten to
0.01 instead of the current 0.1. Apparently it's only a matter of a largish
box in which the media scatters too much, thus making for a thick density.
You might need to tweak it further, for instance the 'extinction' might be
able to go higher or add slight 'absorption'.

Unfortunately, asking for help with media can entail all sorts of "in the
eye of the beholder" stuff, so you might get varying opinions (even from
yourself) until it looks the way you want it.

My question to you would be: is that stretched background image what you
intended? I'm guessing it's Earth clouds.
