As far as I know you have to put a cube around your scene with some scattering settings - and then move very carefully
Paul has an example here:

Hi Deane - see the workflow Uwe posted above. The 2 biggest issues are 1) you need a lot of light-to-dark contrast to see the rays (see get some real dark shadows in the scene where the rays will shine), and 2) volumetrix cube placement is critical - and you will need to do some experimenting to work it out. Its easy when you know how, but learning "how" takes quite some time.
