how to get realistic sunshine?

How can I get a realistic sunshine effect without dropping to many framerates? The effect must be like when I look at the sun I’m blended(much white). The Unreal Tournament sun isn’t to bad…

Tips/code/links are much apprecited(really need this effect).

Either you use the color matrix, or you draw a big white transparent rectangle just in front of your camera after drawing your scene (much faster I think).

Hope that helps

I’ve tried making a transparent box in front of my camera… The only thing that happens is that my entire scenery becomes brighter, the sun doesn’t matter…

Could you explain more in detail what you mean?
