Hey Mark :

  Brother's in the house , eh ? Uh oh . Explains why you didn't
actually read my mail before replying to it <grin> . No problem,
I'll take just about any kind of reply I can get these days .

   Yes , I do remember those images very well , and considering
the lack of info on RS HDRI usage , they are just as relevant
today as they were then , to many RS users anyway .

  I have Timo's plugin and in case you missed it , here's the
link to outputting RS HDRI .
http://www.3ddart.org/index.php?name=PNphpBB2&file=viewtopic&t=611

  What you're doing sounds very interesting , and now you can out-
put those images in HDRI .

  My point was using an HDRI of a Cathedral interior (only as an
example) to do details on things like the golden Challice on an
Altar . IE : Do the render of the Cath interior , output the
HDRI of that interior (using the Chrome Sphere method) , then use
that resulting image in Timo's plugin (to render the Challice) .

   It's no big idea , just an obvious workflow .

   Anyway , looking forward to your resulting panorama's . I still
have that java 360 panorama program somewhere if you'd like it . A
small blind spot at top too , I think , but zooms and the Real3D
project already has the camera set up perfectly (no RSV5 project
for it yet , however) .

Take 'er easy !
