try this... http://www.evermotion.org/?unfold_exclusive=54&unfold=exclusive
search at evermotion, several tutorials
or use photoshop plug-ins or some compositing program with light-fake effects

You can also try Global Illumination programs such as Kerkythea where it is possible.

SketchUp doesn't feature ray traced lighting in any way. Do you actually mean "volumetric light" or do you mean ray-traced lighting for creating photorealistic renders?

If it's the former then you'll have to be much more specific- what render software are you using?

If it's the latter, there are many render programs out there, Kerkythea being a very popular and free comapnion to SketchUp. I prefer Vray for reasons too complex to describe here.

I think he is referring to particles in the air (dust,humidity,etc..), that cause refraction and reflection of light, thus causing the 'volumetric' effect (beams or cones of light).

Most of the time,volmetric light is 'mimiced' by modelers/render engines ,as the polycount of real particles can be troublesome.....
