Cape Not Showing Up In FBX Import

My character model from Blender has a cape, but when I import the character into Unreal, the cape is only visible from the back. It is invisible when I look at it from the front, even when I apply a material. Is there a reason why it does not show up?

For your information, the cape is just a single sided plan. Also, my character has the Subsurf Modifier on.

Like you said, it’s a single sided plan. As in, it’s a two-dimensional object you are trying to view in three dimensions. It has only one side. So if you try to view it from the other side, it will be invisible because it doesn’t exist in that dimension.
