Innis, Now you have me puzzled and I love a puzzle. Yes, an object that is marked as double-sided should render both sides, because in effect the double-sided toggle is telling the render engine to consider each polygon as two polygons with the normals inverted. If you like, feel free to take this off-list and contact me directly, perhaps sending me your Blender scene file with the two objects as they are just before they are joined. I'm certain we can figure this out. I'd like to export the results and have a look at the .ac file being generated.
