This is true if the non transparent surfaces come before the transparent one in the model. You can do this by reordering part with the modeler ( I think ac3d as a panel to do this ) or by ordering them with animations in the xml file as I describe in a previous thread. It is sometime hard to have the correct ordering for both sides so I prefer to have two single-sided object rather than a single double-sided one. This way, I can tweak ordering independantly for all view directions. This was especially useful for the bridge that make a great use of transparent textures ( look at east bay bridge to see what I mean ).
