It is probably a uv mapping issue. Someone with more max experience can probably answer this, but I remember there being a checkbox of some sort that applies UV to the back of object.

Hi,

the problem is that your object in max only has a single side. the UV Mapping is only applied from the front and not from the back.
I am no max Expert, but there must be a setting where you can make the plane doublesided.

Pandoras Box does 'backface culling'. That means that faces with Normal vector directed to the opposite side are not considered. To solve this you have to create a second face directed the opposite way.
