I made a duplicate of the moonhawk folder, renamed it moonhawkr and made some edits to the car mesh. Specifically, removed the windows and roof to make a convertible model. When I exported the model to DAE (I'm using 3ds Max 2014 Student) it seems to have lost the "shifterbase" mesh, so I removed that from the Jbeam files as well as the windows. I renamed the DAE file and main JBeam file to moonhawkr as well. When I select the car in the game, it crashes. I've read the log file and there are no errors concerning the car. What am I doing wrong? Do I need to rename something else? EDIT: It's clearly not a mesh problem as I replaced the DAE for the original Moonhawk DAE and it still crashes the game.
