That all depends on whether you want realistic or fake shadows, static shadows, or shadows which can move and change, and what it is you wan to cast shadows from, and onto.
There is no built in support in Blitz for casting shadows, but I sell a system which makes it fairly easy to cast realistic or fake shadows from objects onto meshes. The link is below in my sig.
