I need to know how to make a plane as a background that can basically take
place of the black void, but the plane is situated where my object casts a
shadow on it. How do I make the plane where no shadow can be cast on it;
perhaps through it?

Thanks a lot.

    I am not quite sure what you are asking, but I think you might want a)
"shadowless" lights, b) skysphere.

    The keyword "shadowless" inside a light statement will make your light
illuminate your object without throwing shadows. A skysphere is a sphere
upon which shadows do not seem to land and which is, for all practical
purposes, infinite.

    Perhaps if you told us exactly what you were trying to do...

You might consider using a sky_sphere as a background instead of a
plane. You don't get shadows on a sky_sphere, and if you move the camera
there's no danger of seeing the edge.

Or, if you want the background to be a single colour you can use a
"background" command instead of the plane.

If your sure you want to keep the plane, change its finish to 
   {ambient 1 diffuse 0}

I was basically looking for a skysphere. I've got it now.

Thanks a lot.
