This package I found is a lovely set of textures for Stalker OP 2.2. This makes the game look like Autumn Aurora. Sure, OP 2.2 is still a lot of fun, but playing it with Autumn Aurora textures is even better. Having the darker look of Autumn Aurora in Stalker OP 2.2 is the best thing ever if you hate the bright green grass.
This is an amazing mod, it looks so much better than the default, and this is suitable for any Stalker OP player.

Just copy the gamedata.dbz_aa22 file into the OP 2.2 folder and enjoy.
