Gunslinger's Academy is a Jedi Academy total conversion which aims to bring gun combat to Jedi Academy Multiplayer. Features include new weapons, achievements, killstreak rewards, a new combat system, several new maps, and multiple new gametypes.
This new post processing effect allows for point-based sun shafts. Also based on viewangles and Line of Sight

And isn't finished here, i.e. it needs more filtering so that only the white parts have god rays (for example).
From what eez tells me though, the way he set up the sun shafts makes it very easy for a mapper to do.
