I just tried your North figure 8 track and is coming along pretty good. Couple things which you probably already know. There is a big bump coming out of the pit area to the track. Also in WEEKEND mode with 15 AI cars, seems only 5-6 cars come out of the pits. The rest of them start up, but stay in their stalls. Not sure how bumpy you want the figure 8 track overall. It is fairly bumpy all the way around track. Just small moderate bumps, nothing drastic other than coming out of the pits. take care.
Ok, I am aware of the nastiness at pit exit, I've been struggling to get AI to start proper, I noticed if the chosen car accelerates quick off the line it works better.
It was a pain to get L and R lines to work using AI helper app. But something is still awry. Being the track crosses over itself has something to do with it. I actually had to lap pit lane.ai round the circuit twice to get that to work.
I may try other start/ stop times when recording both AI lines.
It worked when I 'got' it after many attempts.
I willcheck tonight, but try looking at ui folder notes for title and what is says for amount of cars.
Regardless, a figure 8 config takes more in depth adjustment to allow all lines to be produced for a usable version.
However...online with "real" competitors is your best bet, which is my target....pliable for multiplayer; for any of my tracks. I do see the high demand for AI amongst sim racers.
The track is this bumpy, I've been on it. The pit road is my custom; there is no pit at the real location.
If I get more request for refunds due to the bumpiness, I will try to smooth it... but I like to keep it real in this case.
