Large stadium backgrounds

Hi lads,

Newbie here so go easy lol.

I have seen screenshots of like the whole screen covered with a stadium background, are they specific packs? or specific skins?

would love to get this in my game,

cheers

Basically both you just have to find a skin that allows for a background kinda like flut skin(you can use that if you like it but there's more options) and after downloading the skin just download a backgrounds pack in "Misc Graphics"
