 1- You can do an animation of this effect by increasing/decreasing Sun Altitude.
 2- By increasing haze half-height you can change the lightened area.
 3- By using atmospheric blue and light decay settings you can change the color of your laser rays.
 4- 3D clouds just make your render time bigger. So don't check it.
 5- Making max. Accuracy values just makes your render time bigger.


 
- Thanks for looking up and trying this effect.
- I think this is not actually a tutorial, mostly a "How to".
- The 4000x3000 render  of this effect took 01:09:00 (1 hours 9 minutes) on an AMD Athlon XP 1700+
