I was changing all parameters of
the finishing of a texture, trying to find
the bright reflection spots of the light.
This were not seen, and the object always
appeared in a monotonic brightness.
The solution was removing the <shadowless>
parameter from the light_sources.
This means that the <shadowless>
parameter changes the finishing.
It does not only avoid
the shadows being raytraced.
