I know you can not actually do this,  but is there any way to make a single
item in the scene recieve no shadows at all from any other item, yet still
have all other items able to have shadow amongst themselves, sort of like a
receive_no_shadow technique?  What I want to do is develop a scene where an
item appears to be behind the sky, but I can't do this with a sky_sphere so
I'm using a real sphere. The only problem is you can see shadows cast onto
the sphere (sky).

Give it this finish:

finish {ambient 1 diffuse 0}

and then it will be fully lit everywhere but its lighting will not depend on
light sources. This should make it look like a sky sphere.
