No area light is used here (I have it available but is not used in this 
scene). Light info is:

#declare Sun_alt 			  = 50;
#declare Sun_azm 			  = -80;
#include "CIE.inc"
#declare SunColor     = Blackbody(6500)*2;
#declare SunPosition  = <0, 0, -2>*10e4;
#declare SunPosition  = vrotate(SunPosition, <Sun_alt, Sun_azm, 0>);
   light_source {
     <0, 0, 0>
     color rgb SunColor
     translate SunPosition
     parallel
     point_at <0, 0, 0>
   }

I am trying to get a simplified version of the cloister (only bounding 
boxes from Poseray) and put it here as soon as I have made it work...
