Volumetric light in Underwater Dynamics DVD

[Satamanster]

Hi guys, i just borrowed the Underwater dynamics DVD from Gnomon Workshop from a friend because we have to do a project in maya for college that envolves this kind of stuff.... The question is, i've scene the intire tutorial and there is nothing on how to setup this light, wich when i saw it on the dvd the instructor already the light set there, ready. I've looked all over the internet, and there is no hints on how to do this for maya software rendering (it has to be since i'm gonna be using painteffects). Any hints you can give me please?

Here are two shots i took from the products page:

(The volumetric light is represented by the rays, not the directional one)

The result:

I would be much appreciated if someone could help me dealing with this... Thanks a lot.
