Hello, I have a problem.

When running in the editor, my project works fine and looks like this.

However, when I export, the lighting is completeley broken and the game looks like this. Also note the wheels jittering.

The project uses the default world environment/skybox and no other light sources and default materials all around. Could you please help me find what’s wrong with my export? I’m exporting to Windows Desktop.
