I think you should stick with your "dreamed" Afghanistan, using 
"reality" (and real scenes/objects) only as a template. You did not 
expect the real "swampy bog"? So, just ignore it and create your lawn in 
place of it. I believe Khyberspace is about that, and not about the 
dirty reality. However, just my two cents of course. :-)

Clumping is the way to go I think. On any grass scenes I have created I would
create a clump of grass (maybe 20 blades) over a small area of a few square
centimeters. (Often I would create an array of clumps with randomisation)

Then repeat the clumps over the terrain, the spacing can then be larger between
'blades' but allows for rougher terrain.

Pretty sure the macro for this grass is in the binaries section on the site if
you want to try it out.

Your file can be found here -

I want to point to another great grass scene.

Back in 2006 there was the last round of the old IRTC competition with
'complexity' as the topic. The results weren't published, but the entries were
collected together with some sources (
http://ftp.irtc.org/ftp/pub/stills/accepted/ ).
One phantastic scene is 'Grassland' by Isaac Kulka.

His image consits of four seperate images (sky, background, mesoground and
foreground.
He uses clumps of grass and separate grass leaves.

Thanks indeed for that Kulka scene reminder, Norbert. Great stuff!

An amazing image. Improved? My minds eye thinks you've added additional 
plants & flowers over the version previously posted? I also don't recall 
being able to see inside the tree's cavity as well - but maybe that's 
positioning of the image on my low-ish quality monitors.

Thanks for posting. An effective, affecting image.

Thanks Bill, your memory/powers of observation are working well. Yes, I rendered
it at a higher resolution a while back (unfortunately the only POV'ing I have
done in a long time) and decided to fix a problem Norbert highlighted with the
original scene by adding some more flowers to the top left of the image.

I cannot remember seeing this image before, but agree with BP, amazing.  the
bark makes me think 'beech'.

(the only niggle (for me :-)), I think the critter should not be .. naked.  a
webbing cum tool belt perhaps)

When I was using my old CRT monitor, the cavity did not show any detail 
in that cavity, but modern monitors make them quite visible.
