Animation on rig_rail not rendering

Hello everyone, i animated a car with a rig in city sample that i attached to a rig and then set current position keyframes.

Animation is clean in playback, but when i render, the car stay still where it is suppose to be at the frame where the timeline cursor at.
Here is a frame rendered, the car stay in the middle of the road while it’s supposed to move forward at the same speed as the camera.

If any of you have a clue i take it. Ask me more i’m a beginner so i’m not comfortable at all !

did you solve it, im in the samee shoes as you right now :slight_smile:
