  Not that long really, only 3 minutes. Appart from near the crackle 
borders, I also permit the trees to fill sometimes an entire cell, so 
this accelerates the rendering and causes the effect of little forests 
here and there. I'm just thinking that the same technique can be used 
with the houses to create little towns... hmmm... interesting.

   :) You know, I expent many time looking at aerial photos of fields to 
try to capture the order/chaos there, but the only idea that poped up 
was the use of crackle.

   Indeed, I forgot to tell you something I discovered about Skylight 
when making this scene (as you are one of the few known users of this 
include):

   I finally found why SunColor seemed always too blue, and it was that 
ovbious that I feel a bit idiot: Skylight isn't a sunlight model, but a 
*sky light* model. Looking for first time at the original abstract 
papers that Philippe Debar implemented, I notice that he only 
implemented the one for the sky light simulation, so the SunColor 
returned it's not the color of the sun, but the color of the sky at the 
sun position. I'm using now instead the Blackbody() macro from CIE.inc 
for the sunlight color, with variable temperature depending on the 
altitude: Blackbody(2000+4500*Al). Of course, I still use the sky dome, 
  and the SunColor for the fill lights.
