Ok... I am not into 3d stuff too much, but I found some models online that were free and looked cool. They were in OBJ and 3ds. I add them to the file structure like the Help file says and they even show up as an option in the models section for the particular Space Station or ship.
However, when I choose one, it usually doesn't show up. I'm not sure what programs produce these 3d files, but they don't seem to work.
What am I doing wrong? Or is there a particular type of 3d file that I need?
