Volume Light Shadows

Problem:
Volume Lights that cast shadows.

I’ve read in the 3D Max manual that you can only use Shadow Maps for shadow-casting volume lights. Using Vray, I have to switch to Vray Shadows or the program will give me an exception. However, the volume light effect will not render. Am I missing something here?

Any help would be greatly appreciated.
