Land_PortableDesk_01_olive_F and I assume other colors of the object is not visible through glass windows of Land_GuardHouse_01_F. Have not yet had time to test all but I imagine it is pretty consistent.
Have also discovered other objects in certain parts of the building will clip/dissapear
Place Land_PortableDesk_01_olive_F inside Land_GuardHouse_01_F and position camera outside the building or in some positions inside.
