How do I change my player character into a morph created in 3D Paint?

So, I’ve created a morph in 3D Paint (probably not the best tool to use but its all I got right now.) and I cant find how I’m meant to import it into Unreal Engine as my player character. Any advice? Like better software that I could copy and paste my completed morph into and use that to import it in? I would appreciate any help given.
