I think the placing of the grass will need a lot more work, at this stage I
was just happy to get trace and eval_pigment working together. I want to try
and break up the grass on the top of the dunes, my next challenge. BTW can I
use an image_map with eval_pigment? then I can paint the location of the
grass. The lighting is meant to be early evening - yes, the sky is probably
too bright another factor to fiddle with!
