Physics Problem (Floating/Invisible Ground?)

All physics objects in my game float a few inches above the ground on impact.
They do collide and bounce, etc. as they should but it’s as if they hit an invisible floor above the actual floor and then they just sit there. I tried it with a basic cube, physics enabled to debug and see if it’s a problem with my gun’s physics set up but it isn’t. This happens to all physics objects in my game on any floor.

Yes, I tried it in a new project and it still sinks through the floor. I had it working temporarily but the car was rotated 90 degrees… I tried forcing forward X on import, I tried rotating the source file then saving that as an FBX, nothing works. It’s either rotated, or the wheels go through the ground. But never neither.

Have you try to create a new level and do those test again? And have you check ground collision box?
