i used a car setup from here http://www.tutorialsforblender3d.com/Game_Engine/Vehicle/VehicleSetup_1.html
aaaand it works very well and is amazing fun to use and so i am trying to use it to make a car multiplayer (drag racing, car sumo wrestling, and car tag!) and i know how to use the split screen camera, BUT when i import two car setups into a scene only one works even when i change the controlls. CAN ANYONE HELP?! do i have to go into the script and change all of the names?
