AtmosFear is a set of mods for S.T.A.L.K.E.R. - Clear Sky that tweaks and expands the vanilla weather system to be more realistic and various.

The vision distances for some weather cycles has been increased (and reduced for other) so on a clear day you can now see almost across the whole area.

AtmosFear: Blowout
This mini mod replaces vanilla blowout sequence making blowouts dark and gloomy, showing strange atmospherical phenomena similar to aurora borealis (northern lights) due to high level of ionizing radiation.

• 3 additional dynamic weather cycles (partly cloudy, foggy, very foggy)
• There are now 7 (instead of 4) weather cycles (clear, partly cloudy, foggy, very foggy, cloudy, rainy and stormy).
• Full weather cycle (static) for Agroprom Underground.
• Altered weather behavior.
  There are now 2 main weathers cycles, good and bad. They change in 2h - 8h periods (depending on the area). The weather still changes from hour to hour within each period.
• Different weather balance graphs for the areas.
  Swamps, Red Forest and Yantar are often foggy. Agroprom, Cordon and Warehouses are mostly clear with more storms. Dark Valley and Limansk are rainy and stormy so don't expect much sun there. The rest of the areas have the weather balanced more or less equally.
• 31 new rendered sky-cube textures.
• 64 retouched, edited and colour corrected textures from vanilla version, StalkerSkies by Cambragol, Panoramic Mod by Argus and STALKER Complete by ArtistPavel.
• Increased vision distance for clear (x3), partly cloudy(x2) and cloudy(x1.5) weathers.
• Reduced vision distance for storms (x0.6), fog (x0.4) and thick fog (x0.1).
• AtmosFear: Blowout (optional) - replaced vanilla blowout sequence.
• Optional high-resolution texture pack
• Included option pack with various tonal range, night brightness, weather periods length and balance settings (see Options section)
