Use the Collect module to incorporate the output light in the 
scene given to the Render, Display, or Image. #!N #!N If 
no light is present in the object passed to the Render, 
Display, or Image tool, a distant light of color [1 1 
1] (behind and 45 degrees to the left of the viewer) 
is automatically incorporated in the scene. A small amount of ambient 
light is also used. Data Explorer removes these default lights if 
any light has been specified. The effect of the system's default

settings of AmbientLight) with the distant light generated by the Light
