Beta Texture Pack
Every texture file is separated by folders and sub-folders which shows to which file they belong and which file the texture should replace. Additionally the texture files are separated by their chunk in the folders.
Be aware that a few textures were removed from the final game release, so you won't find them in the game files to replace.
To install just follow the folder's order and use NFS-TexEd to import the textures.
Once you open the game file with NFS-TexEd, just select the "Texture" in the toolbar, click in "Replace" and it's done! If you wish to add any other texture, in the same "Texture", click in "Duplicate" and name it properly.
Don't forget to make a backup from the original file.
