Importing Models into XNA
If you have custom 3D models you wish to use for your final projects you will need to make sure they are in an XNA compatible format (.x or .fbx). Using Blender to export your models is the easiest route but if you have a different piece of software you prefer to use check out this site: http://en.wikibooks.org/wiki/Game_Creation_with_XNA/3D_Development/Importing_Models to see how you can import your models.
