Hey guys. I'm not sure what the name of the technique is called, but I'd like to place a sun in the sky of my world. Moreover, I would also (eventually) like to have it shimmer/reflect off of my world terrain and water. The sun technique and reflection I mean can be seen in some of the pictures below. http://tinyurl.com/g9pxl http://tinyurl.com/htl7t http://tinyurl.com/gbj6j http://tinyurl.com/h4fx3 http://tinyurl.com/f2wbb Can anyone point me in the right direction to get started with this? Thanks for any advice/help!

The sparkly thing is called lens flare. Here is a tutorial on the Reference section of this site.

The reflection is just that, reflection. The water image looks like it is just reflecting the skybox, which has a big bright spot for the sun.
