I found something similar but it's not solved in this thread: http://www.racedepartment.com/bobs-track-builder/23981-exporting-into-rfactor-question.html So I'm asking again. This is my specific problem. I'm making my first track in BTB and I didn't realize that I use wrong Venue name and Track name. So I want to change it, but! When I change it when I export track to rfactor it disapear from list of tracks. I rtied to delete new and old folder with track, delete .hat file, all files with name of my track (replay, .xml, motec files..) but still cen't get it in game. I also changed xml file in BTB where is written venue and track name, and still no luck. If I change it back to original venue and track name track is listed in game again. I don't know what can I do else. Also, is there some option in BTB where I write track real location and lenght, image of loader or I must change those manualy when the track will be finnished?
