that tut works but it's pretty old..... there's better ways now with Vray's native toolset (fog) check out the following writeup.

Unless it's for an animation, I don't see any good reasons to justify the use of volume fog to get the effect you are looking for in the picture. The same can be done much faster with some decent photoshop skills and I'd bet that was just the way it was done in the picture you've shown. Google "god rays photoshop" and you'll see some tutorials on how to do this. In my experience volume fog alone can never deliver a good enough result and always requires a lot of post work to get a good result, not to mention the huge render times. If it's important to see what way the ray of light is heading, then render out the fog on a different pass with low settings, smooth it up in post and overlay it on your image.
