[Radiance-general] Shadow above highlight?

[Jack de Valpine]

Hi John,

As Thomas mentioned it might be helpful to post the parameters that you 
used to produce the image. Also to be clear, if you "only" want sunlight 
(no sky) then  you should only use the gensky line, removing:

skyfunc glow sky_glow
0
0
4 0 0 0 0

sky_glow source sky
0
0
4 0 0 1 180

These lines produce a sky description to go along with the sun (and 
skyfunc definition) produced by gensky.

-Jack
