It's nothing. I'm visiting my Dad (in San Diego) for the holiday. And I did
have a good Christmas but I have to go home today so I'l post this reply before
embarking on my plane ride home (Hawaii).

The reason why I asked for it is that I have a L3PAO style program in the works
(waiting for L3P 1.4 nudge,nudge Lars ;-) ) and I wanted to build in some post
L3P processing elements like the mesh enhancer functionality.

After further review of my file I noticed that I was mistaken and I'm not using
the setings above but the ones you noted earlier in the thread:
http://www.brickshelf.com/cgi-bin/gallery.cgi?f=92270
If you'll notice that the built in sky sphere has blue which is where the blue
tinge is coming from.

L3P only shrinks parts it find in the LDRAW/PART directory and not custom or
unofficial part embedded in the MPD or otherwise.
Since it's not recommended that you add unofficial parts to the LDRAW/PARTS
directory, there 2 possible reasons why mine are shrunk:
- I manually added the part shrinking code to those parts that weren't shrunk by
L3P (most likely)
- I used a private beta of L3P 1.4 which may have corrected this problem (not
very likely)

No problem. I like this thread and my interest in HDRI has been sparked by
Koyan's reply.
