3D Ball - Lens Flare effect
If you have seen the article on "Creating a snowfall effect" I have made for Indezine (Click here to enter link), here's another sample you can take a look at. Following through the article, you can also make use of the snow fall to create lens flare effect on a ball to make it looks realistic. To achieve this, you will need 2 instances of "snow", where the first one will be bigger and has the transparency set to 20%. The second one will be smaller, which will overlaps the first one.
