Greetings!
   I'm working on an animation where one scene is using a
smoke-filled solid.  A test render for proof of concept
turned up a wierd error in the later frames.  I've posted
a ZIP file on my website that contains:
  1) three of the 100 frames
  2) POV and INI files (facetest.pov)
  3) necessary GIF images and .INC files to re-render the animation

This *may* be related to the well-known 'lathe' bug, but maybe not since
the problem shows up differently as I translate the media (the
solid it self does not move).

If someone else can offer any comments on how to avoid this problem,
your help will be GREATLY appreciated.

I can't post to the bugreports group, or I'd have posted this there.

Thanks in advance for any help/comments!

It would seem to be a type of coincident surface problem, the back (or
bottom) of a HF would be where the box surfaces are. Either scale the box
slightly smaller to overlap into the HF or translate into it a little.

I changed the file around some that way, plus other stuff, and attached
here.
