I am working on a small tool that will create a LYT file given an image of a track (pencil trace). This is one of my first experiments. You are more than welcome to try it, my PB is 1:16.89 with the FBM on default setup with 25% fuel (although I am driving with a mouse, so there is lots of room for improvement ). If you want you can also reply with a layout that you want me to try. All I need apart from the picture, is the start point, the direction at the start and the width of the track at its narrowest point (to extract the scale of the track).
