Lightmapping Static Objects without Receiving Shadows

Hello!

I marked some objects as STATIC because i want them to CAST shadows in other objects, but they WILL be moved by other script (like a rotating ball) and i dont want those to recieve shadows on them, how can i acomplish this?

I tried un-cheking the "Recieve Shadows" check in the Mesh Renderer but that didnt work, also, if i make my object non-static it wont cast shadows on the other objects.

Help apreciated.
