Hi, Im new to this site and to custom content in general. i recently downloaded a floorless track and car type from cs depot and when i tried building the roller coaster the track is upside down. Is something wrong with the download or did i do something wrong?

well at the beginning in the circle of track angles, there should be 2 options, and you have to pick the one at the bottom to get it upright

Build one piece of straight track first, and then put in the station. This will keep it upright
