Noob question about Glass meshes in unreal

ChrisKiser

Ive been away from unreal for a while.  When creating glass meshes for window or doors, does the mesh need to be a solid shelled shape with thickness or can it just be a single flat plane?

Thanks.

Single flat plane is fine. If you can see the glass from the opposite side, then duplicate the plane and flip its normals.
