FGear Vehicle Physics (v1.4)

Thanks already fixed, it was the new rolling friction.

Hello @lazybitgames My car handles well, but I’ve noticed that at speeds like 100 km/h, when I turn slightly to the right, the car continues to slowly veer to the right even after I release the button. However, when turning left and releasing the button, everything is fine. It seems to be a lateral force issue. I’ve reviewed a lot of data, but I can’t find a solution.

I don’t see that kind of behavior in example project.
make sure your vehicle has symmetry, check physics body and wheel locations, even a small offset can ruin the balance.
does it happen when throttle is on or does it also happen when the car is in neutral?
based on that you may also try to use open differential and see if that makes a difference.

Hi, I made a simple model but nothing, it keeps rotating that way, I don’t know what to do

do you use convex casting, if so try ray cast and see if that makes a difference.

can you recreate the issue with a car model from the example project, if so send me the json of the vehicle and point out the mesh to use, I could help you if I can recreate the issue.
