This mod adds some high resolution, rotting-flesh style skins to the zombified stalkers found in Yantar and other areas.
This download also includes an .ogf file modified so that the Monolith stalker who shares a skin with several of the zombies does not also change.
Coincidentally, it actually seems to unlock a Monolith skin that wasn't previously in game, in place of the unmasked Monolith stalker.
To install, simply extract the directory to the Gamedata folder in your mod-ready installation of STALKER.
These skins are primarily based on the unused Tark, Dwarf, and Zombie skins found in the extracted texture database.
These textures are also bump mapped.
