Thank-you, but alas, neither of those work! In fact, they both render
identically, taking the same amount of time. (And I did check to make
sure that I was modifying the right bit of the right file...) I even
tried going as far as samples 1000 and jitter 0.01 but that had no
effect either. Even changing the sampling method produces images that
are *pixel identical* with the original. (Changing the media type from
scattering to emission produces glowing clouds with the same artifacts
in them in precisely the same place.)

Any ideas?

Incidentally, what is jitter, and is it safe to use in media when doing
an animation? (The documentation on media sampling mentions jitter in
passing but doesn't say what it does or what the parameter is. I'm
finding this to be a common theme in the Povray docs, unfortunately.)
