Hi John,<br>
<br>
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:<br>
<br>
<pre wrap="">skyfunc glow sky_glow
0
0
4 0 0 0 0
sky_glow source sky
0
0
4 0 0 1 180</pre>
These lines produce a sky description to go along with the sun (and
skyfunc definition) produced by gensky.<br>

You'll note on this image, that there is a strange shadow on the ceiling.
I am unable to figure out why.

John. I can't really explain what's going on but have you tried to
increase your "-ab" value? This should provide you with a more
even light distribution.
You can probably also change other values like "-ad" or "-aa".
But you didn't comment on those so I can't say if there is potential.
Thomas
