I ran into a situation guys.
Here is a the situation. I first finish my model (both interior and exterior models). I select both of them, then I go to Export Selected. I first try export it as a scenery file so that I can get to the set up tabs (I'm trying to do this so that I can get to the *.x file [interior model] ). But instead of doing that, the computer acts as if I exported it as and *.mdl file (It just exports it anyways without letting me go to the setup tabs).
I know many of you people have gone through this situation before and have managed to find a way around it. Now I need help from you people.
