Ok I have a problem when importing pillows I made in blender into unreal. As you can see in the picture there are two holes on that side but none on the other side.
I tried UV mapping but when I import it with uv mapping and add material it looks awful.
Any help would be appreciated.
That was one of the most useful things someone told me, but when I use it the faces look like the picture. When I select one and flip it the red becomes blue but the blue becomes red.
I tried different things like subdividing it, moving faces, it seems to fix it but when I import it to unreal it still has the holes.
