This blend is a demo for creating a simple lens flare effect in the BGE. All that is happeneing is a ray is cast and when it hits a circle around the sun, some math is done and the alpha values of some things are the results of the math. you may need to change some of those values if you will implement this into you game. Also, a new addition, those little circle things just like a real camera has.
I hope you find this blend useful in your games :)
Don't see much of this stuff in BGE! Great job :)
