I am trying to get a long vehicle like a train carriage to follow a path. Let’s say I have a simple elongated plane. I want the middle of the front edge and the middle of the trailing edge to be clamped to the path.
I have tried a few rigs including empties that are clamped to the path but I can’t get the plane to follow the track how I want it to.
Most of the suggestions I have seen end up in deforming the carriage or allow the carriage to pivot in the middle. For me it is essential that the ends of the carriage stay on the track. I can make one end work but not the other.
