A track model or course model is a model that a track/course is supposed to use. There are 40 available ones, but not all of them are used.
Change track model Edit
In order to do this, the player must bring up the debug menu and go in any debug option that has the scene editor menu.
Once this is done, go to TERRA and now you can change the track model. It won't affect the track itself. Be careful; the game might freeze or even crash if you are not careful, especially 20, 34 and 35 (marked in bold). Here is a list of the track models:
