Here I have tried to put Maracana Esadio (id=276) from fifa14 into fifa15.
The result is that Maracana Esadio is compatible to the format in fifa15. I just replace the Etihad Stadium(id=246).
Though the crowds file can't read correctly, the other fx, stadium rx3 and stadium texture work...
Recently I start to edit the UEFA Champion League stadiums and I have finished several ones.
here come three UCL stadiums' screenshots.

i've changed intro background pictures of fifa11 using Texmod. However, i don't know how to make it more easier without texmod way.
Here are some screenshots about this idea.
