Same here. In my newer message "Some grass" which you'll find below, I've
tried making the grass a bit more saturated. Still not quite as green as in
the photos though, because that just didn't look right in this image.

Nope.

But the whole concept of my grass is that it's a texture, not individual
blades of grass. So I have only two objects in the scene: two copies of the
same height_field, one translated sligtly above the other.

With my method memory and processing time is absolutely no problem, no
matter how big the field of grass is. :)
