I just built my first car in Automation and when I exported and spawned the car in BeamNG the car wouldn't drive. Also after going to the main menu wheel and back into the game play the speedometer and other UI would disappear.
Are you new to BeamNG? If so, the driving controls are the arrow keys so that might be where you went wrong. If you're familiar with BeamNG's controls, maybe 0.25 broke the exporter
I'm pretty sure 0.25 broke the exporter. Had no problems before but since the update I imported a few cars and none worked..
