Camera follow a 3d path problem

Hello,

My goal is to create a 3d “road” and make the camera follow it (like it’s driving on it).

I succeeded to make a null follow it but when I parent the camera to it – the camera jump to another place (when there is a change direction).

How can I fix it?

Should I use another workflow to achieve it?

My workflow was:

1. Creating a road with the pen tool (stroke on, no fill) + making it 3d.
2. Creating a null + making it 3d.
3. Copy the path of the road + paste it on the null’s position.
4. Parent the null to the road.
5. Then change the x rotation of the road.
6. Orient along path – the null.
7. Create a camera (one-node) + parent it to the null.

Now there’s a jump in the camera position from frame 0:20 to 0:21 (in the position keyframe of the null).

*I also tried changing the anchor point of the null to the middle – but it didn’t work.

Thanks in advance!
