Hi folks. I'm new to designing tracks for Assetto Corsa. At the moment I'm trying to make a track using Race Track Builder version 1.3. I've laid down the main track, creating fences, pitbuildings and a pitlane that extends out underneath the main track. I've also placed the car symbols on the track before the start line and so on. I've then saved the track through the AC editor and placed the Kn5 file into "assetto corsa/content/track folder. (not the documents part) I copied and pasted the the "ai, data, skins and ui" folders and the map file from the magione track, and I've changed the text in the ui_track file to match my track. I should have done anything correctly, but when I try to load it in the game it says "loading trackname" and then it goes back to the main menu. It won't go on loading the cars and so on. I'm using version 1.14.1 of the game by the way. I could really need some help with this one. Note: I have a thought. Could it be because one part of my track goes underneath another part, making some sort of conflict with the ground?? Help! //Paul.
