> Is this what you mean by shiny?

Well, yes and no.  You did make the white sphere shiny, which looks
fabulous.  Due to the radiosity, however, it also now reflects the green
sphere.  When seen with the whole scene, this does not look so great, IMHO.

Is it possible to achive the shininess of the white sphere without this?

Thanks,
Hershel
