New game development

Hey guys I’m making a brand new indie horror game and I have no experience at all and I’m using unreal engine to make the game and its inspired by escape from yandere but with a different twist so I got the anime girl but she was made for unity and that’s why her eyes are so glitchy can someone help?

What you mean by eyes so glitchy? explain in details what’s happening, are you importing this character in unreal engine using ue5 skeleton ?
