Hi all,


time enough).

My "water" is a hollow box and the camera is inside. Photons are stored and
reused in a second render.
If I use "double_illuminate" together with the grass mesh, no fog can be
seen.
Grass and trees are only placeholders, but this little problem is
irritating.

Any suggestions?

Norbert

I 'm sorry I can't help you with your problem... I can only say that what
you've achieved is beautiful.

Congratulations,

Fernando.

Try scattering media instead of fog.
Looks good so far. How about adding fresnel reflection to the water?

Entering two rounds in sequence?  You must have a lot of spare time...

I think media would be a better solution anyway, with scattering you could
even show the shadows of the trees...

I think it looks fairly good already, i don't look at water surfaces from
below very often so i'm not completely sure... ;-)  In contrast to water
from above you have the effect of total reflection at shallow angle.

Maybe try raising the minimum reflection to just a bit above 0.  In
addition i suppose media could also have a good effect on this too.

Not so much as I want, but I know, what you mean.
And you? - two entries in one single year; some people might think you are
exaggerating.

Are you trying to say i'm unproductive? ;-)

Sometimes it's simply more appealing not to have a fixed topic and a
deadline, at least this is more cooperative to real life obligations...

Well, maybe you should add some trees behind.  I think some shadowing
would improve it although radiosity would be quite mandatory then.

I would never risk such an assertion!   though...  ;-)

Are you actually aware about having set up the record for the longest render
time (ca. 12 days)
of all IRTC entries?
Although Gena Obukhov with 83 h on 15 Dec Alphas
(http://www.irtc.org/ftp/pub/stills/2000-08-31/gosea.jpg) and Claudio
'Naxos' Gallego with 235 h on a 4 processor machine
(http://oz.irtc.org/ftp/pub/stills/1997-02-28/bar.jpg) perhaps beat you in
terms of Tflops per entry ;-)

Nothimg is ready. Plants, trees, heightfield and water are only provisional
to get a quick impression.
