Creating shadow in the sphere in 3d studio max

Hi,

How do I accomplish to do this?

I have created a sphere and defined it to use diffuse color with amount of 100 (also to use texture of my own), reflection map with amount of 20, to use anisotropic shader with specular level of 30, glossiness of 10 and anisotropy of 50.

You can see what kind of spheres look like now from the picture in the url http://www.kolumbus.fi/arsi.rantala/boltsit.jpg
