Exterior material showing on interior wall of room with vaulted ceiling

[slidnbob]

I have a room with a vaulted ceiling. One of the end walls is the lower section of an exterior wall above. In other words, the vault cuts what is an upper story exterior wall. I can't get this interior portion of the wall to show something other than the material of the exterior wall above.



I found a forum thread from almost a year ago about this and following the suggestion there I changed the specification of this wall to set the "Lower wall type if split by butting roof" check box. The wall continues to show the exterior wall material. Any help appreciated.
