.:: Sky4CE SkyGRAPHICS Mod v2.0 RC3 ::.

  This mod introduces advanced shader technology known as Parallax Occlusion Mapping in the game of S.T.A.L.K.E.R, never seen in any videogame before (except some next-gen games which are still in development, e.g. Crysis , Unreal3 and others) The mod is based on the original Parallax Occlusion HLSL code (Policarpo2005, McGuire2005, Tatarchuk2006), heavily modified by Sky4CE to allow for a considerably higher performance and maximum optimization. You might have heard of  Parallax Occlusion Mapping being referred to as Steep Parallax Mapping, Per-Pixel Displacement Mapping With Distance Function, Relief Mapping, Interval Mapping - all of those are alternative names for Parallax Occlusion Mapping. This technology creates a very close-to-life illusion of true relief , turning flat textures into something that looks much like an actual relief made of polygons. A similar effect can be  achieved via Bump Mapping or Parallax Mapping, but the difference between Parallax Occlusion Mapping and these two is utterly astonishing.

  Also Mod adds :
  - Motion Blur, which does not blur the weapon and works during sharp turns.
  - Depth Of Field, distance blurring.
  - Screen Space Ambient Occlusion, imitation of global illumination.
  - Sun Shafts (God Rays), rays of light.
  
  Motion Blur not depend from console parameter r2_mblur, and also does not demand additions key -mblur in a label of start. If you want it is possible to switch off any effect in a file of options SkyGRAPHICS_options.cfg, in the same place it is possible to change effects parameters. The file of options is in a folder "..\gamedata\shaders\r2\SkyGRAPHICS_options.cfg".

- WARNING! -

To get this stuff working, make sure that:

1. You've got a graphics card that supports DirectX 9.0c  (Pixel/Vertex Shaders 3.0 or higher). DX8 cards are incompatible with this mod due to obvious technical reasons.

2. You are running the game using the DX9 renderer (adjustable in the graphics options, also known as 'dynamic lightning'). The mod won't work with DX8 and it incompatible with this DX8 (`static lightning`)

Installation:

 Look into the folder of the mod package, find the gamedata folder and copy it to your game installation folder, overwriting the original gamedata folder. 
...enjoy :)

Possible compatibility issues:

This mod is incompatible with any other shader mods, but campatible with any non-shader mods !

This mod only runs on following videocards:
 Nvidia Geforce 6200 or higher / ATi Radeon X1300 or higher.

Version 2.0 RC3:

- Parallax Occlusion Mapping ;
- Motion Blur ;
- Depth Of Field;
- SSAO;
- SunShafts(fixed light bug);

Known Issues:

- Shot decals appear incorrectly, can't be fixed so far (since they're rendered via a fixed function pipeline)
- Motion Blur is more appreciable at smaller fps.

If you find a new bug, please email at Sky4CE@inbox.ru me and don't forget to attach a screenshot.
