Perhaps try browsing all files for the game S.T.A.L.K.E.R. Shadow of Chernobyl and upload any files you want to share or are missing. This is the only information we could locate:
This mod drastically changes the look of the game to use more realistic light and shadow.
Much adjustment of "tone mapping" and "an optical degree of a day" was adjusted. It is effective too much and the bloom which is not realistic is pressed down as much as possible. The sunlight to pour moves to real time. The sun rises in the east and the sun sets in the west in the evening.
This is a beautiful looking mod and a recommended download.
