When I try to assign throttle nothing happens. I can assign everything else, brake , steering... I can assign my clutch pedal to the throttle but not the gas pedal. Any help would be appreciated. Thanks.
When you press play, there are 3 choices, play rF2, launch the Graphics Config tool or use the Moddev version. That is the old old old UI that was intended for modders to use to quickly test their work. Also, in the new UI, before you try to assign, make sure you don't have some other command associated with whatever joystick input and axis your throttle is using.
