Nothing is work, and I just wanna know why. I tried so many different orientations, adjust the height countless times. The only time it work was when the pit was loaded upside down and the person was upside down as well. Like I said I just wanna know why and how to fix it so I can test drive this track.
No it doesn't make a difference. Your track loads fine here..... well AC_START_0 is pointing in the wrong direction... but other than that. It's okay for a start. You only have a starting grid and pit numbers of 2. But in ui_track.json "pitboxes" is set to 24. So lower your opponents to 1 in race settings.
It's weird. I just got in from work and tried just using all new files after seeing your post, and it worked smoothly. I wish I thought of that, but I figured I messed up my setting somewhere down the line.
