Awesome job with the alternate shorts. Can you please upload your rx3 files with all the variations of the kits? And possibly your db file if you have already added all of these kits to your FIFA game?
some of the shorts need to be updated
because they don't math the shirt color tone ..
for exapmple .. Everton shirt is dark blue .. and you made the short lighter than the shirt..
check the EA kits to match the colors ..
