hey everybody, I think I have a hint about the bouncing hairs ingame, though I can't guarantee nobody this will work. even if it worked for me. this morning I wanted to play a match and when I entered in the game, surpriseee, on all the players that I've converted from Fifa 16 and 14 hair got problems ingame. I said ingame because on EDIT PLAYER section, everything seemed to be alright. well, I resolved the problem in this mode:

I've changed only one setting, I've put Rendering Quality from low to high and now everything is ok. everyone that have this kind of problems ingame, give a try with this solution and let me now if something has changed. If everything it's ok, I will continue uploading faces ASAP.
