Thank you Thomas. Indeed there was this danger - but in the end it became clear,
that I want to improve by making other images. There is a subtle intuitive
voice, which guided me. I simply wanted to exclude superficial rational
reasoning...

No, I used my two machines - the first for doing all the changes and the second
one for rendering. The second machine with 64 Gb RAM is loud and can heat my
whole passiv house - so my window was wide open all the time since xmas ;-) .

My rational side says such things are and will be inevitable. Personally I
conducted some scenario exercises with similar topics in my compony and in the
beginning I was shocked by the outcomes - this pandemie can lend to very deep
economic recessions - and wars.
Times are becoming even more interesting (in the chinese sense - may you live in
interesting times)...

Hi Norbert,

3 months well spent!

You really are the master of this kind of nature image, certainly what I
inspired to achieve on my attempts but never had the skill and patience to
achieve this level of detail.

Glad you provided the extra large image and also the animals only version so I
could zoom in and spot them. The one I still couldn't see was the Squirrel but I
think even when you don't see/notice these they still add something to the
image.

great work as always.

Sean

Hi Sean,

the squirrel was introduced in february after several previous relocations. But
a later tree needed for shadows hides it now.
Like other meshes I downloaded a free low polygon model without textures and
used the nice displacement feature of Poseray.
Displacement was used on all visible trees and several animals to prevent smooth
shadow borders.

Regarding skills - I envy your modeling and texturing skills since your late
IRTC entries and of course Povcomp. In comparison I'm only good at throwing
objects together in a more or less pleasing manner...

Hopefully we can see more new images from you.

Regards,
Norbert

Don't we all.   He's a singularly focused madman.
Luckily for us, he uses his superpowers for raytracing.  :D

Yeah - sure.  And [the late] [great] Neal Peart was only good at tapping out a
beat in a more or less pleasing manner...  :P

> Hopefully we can see more new images from you.

From both of you - please!   Amazing scenes such as this one inspire me and get
me to think less about technical / engineering / math projects and more about
real scenes.  Especially when there are little notes on how-to and some pearls
of technique wisdom sprinkled about like breadcrumbs to lure me down that
path...  :)

Thank you very much!

I'm sorry about the death of Neal Part. In the eighties I was a big Rush fan -
and drums are my favourite instruments (my biggest heros haven't changed since
45 years - Billy Cobham, Ginger Baker and Jon Hiseman...)

Perhaps I should publish some of my methods to throw objects on a scene :-).

By the way - I found a way to fake translucency mapping when using alpha mapped
objects like leaves. Sometimes it is annoying to see partly transparent twigs
when using backlighting and double_illuminate.

I`ll download this test-scene to pb-sf.
I used this method on the big oak left of the center (it's barely visible even
in the big version).

Regards,
Norbert

Lovely mallards! But I still miss a long-haired mustached olive-skinned 
swamp gypsy wading waist-deep through this swampy creek... or, maybe, a 
lynx on the prowl!

Ars longa, vita brevis (hopefully not too short!)... how much total RAM?

Let us all hope you can render during the coming 150 years... 
Transhumanist technologies will also work for the good of raytraced art!

See you in Khyberspace!
