Yes! First textures imported to FIFA 17

Here you can check Portugal and Barcelona kits imported to FIFA 17. Both kits have been created by Emiliano Videla. We were also able to import banners ( check out real madrid ones ), adboards, stadium dress and even a hair texture ( Messi )

Tool that allows importing textures is still under development. Good news is that since FIFA 18 is also powered by Frostbite Engine we will probably be able to use the same tool to import stuff to the game.
