Wow, yes, Capt! I want to know how you did it, too! (Will be patient for when you have the time to describe it.) I haven't had much luck with it myself so far. I get rays okay (by replacing the sun with a volumetric spotlight, and removing the volumetrics from everything else), but they are not so delicate at yours. At this point, I've gotten sidetracked to figure out why they're doing what they're doing on my end. The effect makes it look like intense ambience mixed with soft shadows, which is weird, but I'll keep poking at it. :)
