I traced this up to 1280x1024, with the resulting two images (we'll bypass
the scene data for now). In the wetnes hf file (actually it is a severally
cropped portion of wetnes) you can see the areas that are suspicious. Then
you can see the error in the reflection of Silty. It's hardly noticeable,
but I thought I'd ask if this is a known thing, or is there something
obvious to any of you? :(

I'll search through the faq's now! :) heh

It's hard to say for sure but it may be that because the
extrusion there is so pronounced it is confusing pov about
which side is the correct surface normal for that area.
Or perhaps the extrusion is the closesest object to the
light source and is giving more diffused lighting reflection
than the other rougher elements of the scene.
 Perhaps it is related to the normal average bug that is fixed
in the bug fixed version of pov now being release on compuserve
but no where else yet but hopefully soon.

Aw, man! You had to say that! [sigh]

Well, I'll try to piece it together another way.

My fix came about as a result of moving the camera slightly, and adding
additional waves, and turbulence.

now this is good, but I think it is too brightly blue... too much light
perhaps ???

A bit darker and it would regain some mood again..

I'm looking a bit on creating a pond, can I have a look at the source,
or some information on your technique ??

Heh, I'm willing to share.

  I used an algorithmic approach to lay the bricks (kinda random, but still
a little linear). The water is merely an hf_gray_16 generated hf with the
properties of water, and a plane with the same properties. I added a media
type Sun. As you pointed out I needed to adjust the reflection_exponent and
I also added phong highlighting to really help bring out the sun.
  I used two files to do this, but I'm convinced it could be done in a
single file. Certainly, the way I coded the hf tga selection for each frame
could be better written.
  Write me and I'll email you the code, or if someone else requests it I'll
post it on text scenes.

Ahh, this explains a lot to me. And, I don't think source will be
necessary, but I'm not final on this, perhaps I'll come crawling to you
if my own attempts fail. :-)

A very good image, thankyou for sharing it with us.
