Hey Dan,
Thank you for the quick reply.
I have made the alterations you suggested. Set end var to 20, and set key frames at the start and end of the comp for the travel slider, starting on .05, ending on 100.
The Front Carriage now moves along the path oriented the correct way, but every now and again it twitches and points in a different direction just for a split second then returns to face the correct way.
The trailer is moving with the Front Carriage but it is not orienting to the path.
Any suggestions? I can repost the file if you’d like to check it out.
Cheers
Kieren.
