Here's my little point in case related to this discussion about improving the spotlight appearance:

"If it's possible to stack spotlights one over another, why not try with sunlight in order to make godrays great again?" I thought, inspired by KlausK's initial achievements.
The rule is simple and the concept has been proven I guess as you can see from another image - the more suns you have the smoother the crepuscular rays will be:

There is one disadvantage to this otherwise useful method - each additional sunlight adds substantially to the render time. Which perhaps you wouldn't mind after all upon doing final render.
Anyway, as per Oshyan's suggestion (and Bobby's cheerful encouragement) I am posting a clip file with my setup, so you can have a look at it and tweak it.
It's nothing special really, not much modifications from the defaults and it takes just a few minutes to prepare it from scratch. But there you go anyway lazyboneseses. :D
Just follow instructions and, if you have patience, try to experiment with more sunlight sources or maybe some other options.
Great, off to my workstation to check this out...thanks mate.
Thanks!
