Unfortunately, I'm having a bear of a time fixing this.  Still working on it
though.  Any experts on scattering media want to give me a hand?  I need a
cloud cover with a bright patch in the center, but foggy by the edges, and
thick enough that you can't see what's below throughout.  I I lessen the
density, the brightness fades to the center, but so does the opacity.  What
I'd really like is an opaque cloud layer with something bright underneath,
but doing it the naive way (a cloud layer with a bright object underneath)
doesn't seem to be working well.

Drat.  You noticed. :P  The algorithm I use is a rewritten version of the
mur.inc.  I didn't like the way vertical lines would often appear, so I got
rid of them in my algorithm (as well as a lot of other stuff.  The algorithm
is significantly more complex)  However, I work in blocks, and the curve in
block is separate from the tower curve (they're basically conic sections)
I'd hoped I could hide it in the background... :/

I'm not sure why.  They're both built in to the algorithm in the sense that
there was never anything there.  One problem might be that relatively small
stones were used around them, compared to the rest of the structure.

Yep.  Wall in the works, and is half done (the easy half, sadly)
