Hi,

when I was young I hiked in the mountains (austria I believe) and found a nice
spot with a small creek. I remember this place fairly well.

Here is an adaptation - as in my last images I used a large amount of different
meshes (> 110), resulting in a memory usage of more than 22 GB.

Happy rendering,
Norbert Kern

The Master did it again.

What can I say? It is the kind of scene we would like to emulate but 
somehow we always stay far behind. Very inspiring indeed.

The brook's water is very well done. I guess the surface is one of the 
many meshes? with the proper media of course.

These kind of landscapes are your trademark without any doubt.

What I do doubt however, is whether I could manage a 22 GB memory usage 
on my systems (for rendering the scene?)

Thanks Thomas,
water is a mesh indeed, but it doesn't look very special. I think a heightfield
made with an averaged wrinkles / rigded_mf pattern could do it too.
The water material is simple -
texture {
        pigment {color rgbt <0.25,0.35,0.2,1>}
        normal {
                average
                normal_map {
                        [1      wrinkles 0.04 scale 50]
                        [1      granite 0.01 scale 0.5]
                        [1      bumps 0.14 warp {turbulence 1} scale 0.03]
                        [1      bumps 0.1 warp {turbulence 0.5} scale 0.0003]
                }
        }
        finish {
                ambient 0
                diffuse 0.3
                reflection {0.03, 1 fresnel on metallic 0.3}
                specular 5
                roughness 0.003
        }
}
interior {
        ior 1.33
        caustics 2
        fade_distance 0.4
        fade_power 1001
        fade_color <0.5,0.7,0.4>
}

Starting point of the image was a 76 MB obj file with stones and water.
I split it in 7 parts and used the displacement function of Poseray. In the end
I had 7 large meshes (> 1.1 GB in sum).

Oh, wow, that's gorgeous.

Gorgeous as usual !

Shall we try once again to guess how many animals are hidden there ? ;-)

Can I also ask how you've made or where you've got the meshes for the rocks ?
Those look extremely realistic.

Well, it is perfectly doing its job.

I notice that you use /some/ color in the rgbt of the water, despite a 
transmit of 1. Personally, I have not noticed this approach did add 
anything (I may be wrong) and simply use  rgbt 1, in general. Using 
'filter' would be a different matter of course.

Very good. I am increasingly using the displacement function of Poseray. 
It does not get all the attention that it merits.

I am lazy sometimes - here I started with a transmit value of 0.85 and it ended
as 1 after some trials. For a reason I don't remember I set reflection with
metallic 0.3, so the color isn't completely useless.

That's totally true!

Thank you.

There are only 4 animal types - fishes, lizard, deer and a peregrine falcon.

Many meshes are Daz3D files -

https://www.daz3d.com/stones-and-structures

It's much cheaper than my investments in plant collections 20 years before...

Hmmm. That last is an interesting idea I was not aware of. I need to 
investigate those implications (as also the filter influence, when I 
find some time...).

I have done some testing in the past. I shall try to dig them up and 
post them, especially as a showcase for its possibilities. Your river 
bottom is an excellent example indeed.

This reminds me of my childhood on a farm. I spent quite a bit of time swimming
and fishing in the creek. I saw a fairly large snake in the water once which I
was convinced must have been a water moccasin, and that was the last time I swam
in it. Thanks for sharing your beautiful artwork!

Kind regards,
