The easiest option for Unity would be duplicating the faces. If you don't want that, you need to find a good double-sided shader that supports all the different maps you want to use with right lighting calculation.

There is no 2 sided shader in unity? Then you will need one if you don't want to manually duplicate and flip the faces. I think a two sided shader would do nothing more than viewing the dot between the camera and the normals, and flip the normals when its reaching 90 degrees.

You're better off duplicating the faces, if you use a double sided shader you'll need to create your own shadow caster and receiver pass for the shader to handle that, too.

Better to duplicate the faces in Max. Polygon sub-object mode, select all, Detach as copy and as element, then Flip.
