The .zip contains all the files to reproduce the scene (see images thread:
http://news.povray.org/povray.binaries.images/thread/%3Cweb.548605687a8cfd3894986c380%40news.povray.org%3E/
) the only thing missing is the HDR probe which I cannot distribute but it can
be downloaded from the free section on http://www.sky-domes.com/?page_id=304

Thanks for sharing.

Seems the saved setting (Show* in pov file) are not to the value used
for the complete picture.

Now rendering at 1920x1200 for one of my desktop (need less than 3.4
giga of memory, cool!)

A lot of warning about csg having less than two objects, and
interestingly it triggers a bug in hgpovray (my derivative of povray)
about the spline object... I will have to fix (in hgpovray, not your
scene) when I have a bit of time. ( there is the added access to spline
evaluation at a point... not founding the expected syntax confuse the
parser, it shouldn't).

Once again, thanks you.

Hi,

True, I did not think to comment on the settings, to render that image I used a
two pass method, first pass with the command line arguments:
+RF"file.rad" +RFO

and settings set to:

#declare useHDR                 = 1;
#declare useFocalBlur           = 0; // 1-10  used 6
#declare useRad                 = 2;// 1=load 2=save
#declare radQuality             = 5;// 1-10 1=low 10=high
#declare useSubSurface          = 0; //1-10 used 4
#declare useTestTex             = 1;
#declare showGrass              = 1;
#declare showTree               = 1;
#declare diffTree               = 1;
#declare showMushroom           = 0;
#declare showMoss               = 1;
#declare showDandelions         = 1;
#declare showDaisies            = 1;
#declare showStones             = 1;
#declare isoAccuracy            = 0.005;  // 0.0005 3m27s
#declare showWater              = 1;
#declare grassScale             = 0.75;
#declare grassStep              = 0.9;
#declare showSnow               = 0;
#declare showLilyPads           = 1;


Then on the 2nd pass change the following settings:

#declare useFocalBlur           = 10; // 1-10  used 6
#declare useRad                 = 1;// 1=load 2=save
#declare useSubSurface          = 2; //1-10 used 4
#declare useTestTex             = 0;

Neither render has +AA only very high focal blur (could probably set this much
lower and still get a good quality but I had time to spare).

1920x1200 should be fine but if anyone runs a render at a different ratio you
may find some of the grass runs out, I literally only created the objects where
they were needed for the ratio
but this can easily be fixed by increasing the area covered by the calls to the
add_grass macros.

My PC only has 4GB and windows so really only 2-3 GB is available to POV before
the PC starts to struggle doing anything else while rendering.

Alternatively, you can use the visibility test macro developed by Gilles 
Tran. It automatically looks if an object is visible in the image or not 
when calculating/writing its position.
