An X-Ray 1.5 / STALKER: Clear Sky inspired sky, weather and lighting mod: a 40-minute day of hourly keys, six weathers that melt into each other (clear, partly, cloudy, fog, rain, storm), nine painted skyboxes, rain, lightning with timed thunder, wind-blown leaves, ambience beds, a drained film grade with sun shafts, and a wet-surface lighting model.
