Hi,

I have taken a pre-made character from the internet and added it to my unreal project to program it. When i looked at the character he looked very good but after it was imported the quality dropped drastically and it looked horrible in unreal, especially the hair. At the hair it seems to be an opacity problem, since they are too translucent and I can’t seem to modify that. I have attached the link where the char can be downloaded( - ?page=1&type=Character&order=recent ), I will be grateful if you could teach me how to solve this problem.

Thank you :),
