So I've tried to make a func_tracktrain in the 3D Skybox sync to a func_tracktrain in the regular map. I've tried setting the skybox's tracktrain to the track in the map, but it doesn't work. I also tried copying them and putting that in the skybox, but that doesn't work either. It moves right, but the skybox brush itself is not aligned with the map brush. What am I doing wrong?
