    What's happening there is so-called
    back-face culling
    . By default, only geometry that is facing the camera is rendered - meaning: every object has just one side.

    In custom shaders, you can turn off back-face culling by putting
    Cull Off
    into the
    SubShader
    section. However, this will make the other side lit incorrectly and thus messing up lighting. Not ideal...

    The easiest and better way would be to duplicate the geometry and flip the normals in Blender.
