Absolute Nature Texture Pack addon - S.T.A.L.K.E.R.: Call of Pripyat

This texture pack contains ground and foliage textures from vanilla and from various texture packs including: Ceano's Graphic Compilation, NeilMC's Graphics Pack, Perfect Graphic Mod by S.H.T.I.R.L.I.Z. and IndigoSC's Green Zone.
Textures has been edited on MIP map level which means that every MIP map in every texture has been sharpened gradually according to display distance. This results in overall sharpness of the image.

Ground texture MIP maps has been edited manually to add more features visible in the distance.

Most of the textures are the same resolution as vanilla so they don't require much more RAM to load. You can use them even on low spec machines.
