Hi. I posted the Bryce to POV image in .images and I was wondering if
anyone has a suggestion on how to make the moon's edges lighter, yet not
damaging the texture. Everything I have tried so far has only led to
making the moon too white. Please help.

Sorry I have no idea.
However, I like guesswork, so how about this:
Increase/Decrease diffusion
Increase/Decrease ambience
and
play with brilliance

Just guesses

Did you check the moon texture I posted? I mentioned it in a reply to the
original Bryce post. Basically, try a brilliance of ~0.3

Yes, I saw it. Very nice. What I didn't like was how the bump-map dissapears
where no light hits the object.

I've never used brilliance. I'll go check it out. Thanks.

You must have at least some light on all parts of a normal or it will not
show. Thought maybe the tilde 0.3 for the 'brilliance' was a negative
number, guess Margus uses a tilde the same way I do, short for
approximately. Well, if you want an interesting effect when using
brilliance now that you're willing to try it out anyway, use a small
negative number instead. 'brilliance -0.3' would make the edges, or
light/shadow terminator, of an object brighten instead of darken. Only
trouble with it is that it's difficult to control.

I didn't know that's what that thingy (~) was called. I've always called that


(pronounce like the yn in Grand Canyon).

Odd... I learned that the squiggle used atop an n in Spanish is called a tilde.
WWWebster (http://www.m-w.com/cgi-bin/dictionary) agrees with me, for English, 
and Babelfish (http://babelfish.altavista.digital.com) doesn't translate it.
(It doesn't translate vi'rgula the other way, either.)  I had always called 
the symbol by itself (as used in C programming and web addresses) a tilde, too,
but always with some reservations.  WWWebster tells me that I need not have 
worried, as that is sense 2 of the definition.

The mark you posted, assuming I saw the same thing you saw (an a with a ' over 
it) is an acute accent.  The mark that goes the other way (i.e. `) is a grave 
accent.While I'm at it, the .. is called either a diaeresis or an umlaut, 
depending on usage.  All those marks, and others like the single dot, the bar, 
the circumflex, and the u-shaped-thingy that marks a short vowel, are called 
diacritics, or diacritical marks.

only real use in spanish is to force the pronunciation of the letter U after the

As I was walking to St. Ives,
I met a man with 7 wives.
Each wife had 7 sacks.
Each sack had 7 cats.
Each cat had 7 kits.
How many were going to St. Ives?
