Cape not showing up in unity

Hello people,

My first post here, im quite new at all this and im having a problem with the cape showing in the unity editor from the back its ok but from the front it dissapears (tried recalculating normals) works just fine in blender

what am i doing wrong ?

 

Just duplicate your cape in your 3D editor but flip normals of this duplication then join it with the original cape and finally reimport it to Unity.

 

Thank you very much ! that was it
