>&#13;      	Blender provides a number of very interesting settings to complete
		your renderings by adding a nice background, and some interesting
		'depth' effects. These are accessible via the Shading Context (<B
CLASS="keycap"
>F5</B
>)
		and World Buttons sub-context
		(<B
CLASS="guiicon"
>&#13;  		<IMG
SRC="PartM/world/gfx/WorldButton.png">
  		</B
>)
		shown in <A
HREF="c5652.html#BSG.WOR.F.S68.101"
>Figure 1</A
>. By default a very plain uniform world 
                is present. You can edit it or add a new World.

><TT
CLASS="literal"

			the gradient occurs on the zenith-horizon-zenith colors. Thus, 
			there are two
			transitions on the image, which reflect the camera rotation
			but which keep the horizon color to the center and the zenith
			color to the extremes.
