I tried importing this CC4 character from CC4 to UE5 and this is how it looks.
See below original in CC4, then in UE5.
In addition to this issue, all of my previously imported CC4 characters are now experiencing this same "bleaching" in the face. This never happened before and all of these characters were working flawlessly before today.
Any ideas ? I've done several other characters and they came over fairly well.
CC4
