Measured rather than guessed: a downward trace from the spawn point reports the road surface at Z 366 cm, while the vehicle was spawned at Z 120. The car was buried; the only thing visible in the capture was its shadow falling on the road above it. Spawn is now Z 470, the camera aims at 430, and it settles at Z 470. Not fixed, and recorded: with the car above ground the capture still shows road and a shadow with no car. Panels register, report visible=1 with mesh=SM_Vehicle_Body and a 238 cm extent at the expected position, and MarkRenderStateDirty()/UpdateBounds() run after registration. The shadow proves a collider is there; the visible geometry is not. Screenshots/README.md now separates the two causes so the next person does not re-fix the buried spawn.
