Functionality description:

Not that long ago we served you an add-on called "Greener grass textures". It made the colours of the grass more contrasted, so it looked better.
"NPT&C" World Cup Edition is a file, which completely changes the pitch!
It definitely gives a better visual effect and also... makes the match engine work faster. I heatly recommend this file.

Installation manual:

Extract the "pitch" folder to: C:\Program Files\Sports Interactive\Football Manager 2009\data\sigfx\meshes\ replacing the default folder.

In case of Football Manager installed through Steam the directory path is: C:\Program Files\Steam\steamapps\common\Football Manager 2009\data\sigfx\meshes\.

Before installing the add-on it is recommended to make a backup of all the files that are to be replaced, so at any moment it is possible to change the things to the previous state without reinstaling the whole game.
