Just had to try and see it for myself... and find this invisible wall a lot of you are raising here... Watched a few GT4 replays and all cars behaved well around the track... With one exception, the Subaru BRZ GT4 '15 (v1 reworked by Beezer back in Mar2020) was been driven by AI when it jumped off the road with a lot of sparks around T3 as posted by
@Paulo Ribeiro...
Checked track and found line-marker (1WALL_46) that was raised here. Checked car's collider just in case and found it to be way off when compared to the Toyota equivalent... so as a quick fix, copied the 'collider.kn5' file across, watched the same saved-replay and no more issues for the Subaru on T3... note: check the cars' collider also...
would not know how to adjust the track-issue, so if someone knows and is willing to share some time and intel, more than happy to learn...
