Need help with creating faces


Club Supporter
Since I can't find any tutorials or threads that help me, I just ask here:
I wanted to start creating faces and followed a Fifa 21 video. Everything went well until I hopped into the game. The head I created is invisible and I can't really tell what I did wrong since the head is looking normal in FET.

Anyone know a fix?
