I've been building my first track (road course) using BTB 0.8.3 Pro and have pretty much gotten the layout I wanted, and added a bunch of details in. The track is perfectly driveable in the game of course, although I start off on the terrain somewhere...that is due to the lack of a proper AIW file, I know. Track building is addictive and has cost me a lot of sleep in the past week! My question is probably a dumb one, but how is the start/finish line position set? I go to the edit start/finish properties menu -> timing gates -> move. Then click "Manually" for the Start dropdown, where BTB crashes on me with an Unhandled Exception error(all the options in that dropdown crash). I am in 3D view for this, but have tried other views to no avail. Can the start line be set with the ISI AIWCAM editor? I am afraid to spend many hours finetuning the AI while BTB crashes on me for the simple startline problem. Thanks in advance if anyone has any advice.
