Thanks.  This is a potential bug.  I'll look into it.

Bug warning:

You may run into problems with photons in media.  I just noticed a bug where
media is attenuated at the wrong time, so the last section of media might
not be calculated.  Try to have an empty space between your media-containing
object and the surface that gets hit by photons to make sure things get
computed correctly.  Photons on the surface of the media-contianing object
or on objects within the media may not get attenuated.

Hmmm... Looks like the site is down.  Guess I won't be uploading that bugfix
tonight.  Well, anyway, if anyone wants to mirror it they can, just please
mirror the update once I get a chance to upload it, too.

The following is what I get when I run Jaime Vives Piqueres
test04.pov & i_stsky.inc . The same stuff runs fine in official
POV3.1g .

<snip>
 Warning Stream to console.......On
  dfactor,            // darkening factor
  border,             // width of change zone
  fstart,             // filter for lower layer
  fend                // filter for upper layer
 )r <----ERROR
<snip>
\i_stsky.inc:32: error: object expected but undeclared identifier 'r'
found instead.

Does anyone else get this?

The files are at Jaime's site in "CLOUDSCAPE" or I can send them
to you if you don't already have them.

  Does this work?

Is there any reason you want it to ?

  No, but there are many reasons why I don't want it to work.

	I've mirrored the windows binaries there:

	http://www.enst.fr/~jberger/uvpov6.zip

	(there's no link on the web page and I'll probably remove it when
Nathan's site comes back up, but for the time being, there it is...)

I was experimenting with the new radiosity today and I noticed when I changed
resolutions that the brightness of the scene changed.  I had some lights in the
scene that I commented out so I could test some ambient objects.  At first I
thought the brightness was different because of the different resolutions, but
apparently the radiosity cache file (from when I rendered it with the lights in
the scene) is being kept but is only used at a specific image resolution.  I'm
not sure yet but it sounds like that old global variable bug might have creeped
back in.
