So, I have found a workaround for this issue. However, I’m not sure if the original designer intentionally made it so this function could not be directly accessed by users, or if it was by mistake.
Given the lack of documentation for the FPhysXVehicleManager class and that it’s source is in a private directory, it’s more than likely that you are not supposed to directly access this class.
If you can give me some insight into what you’re trying to achieve, maybe there’s a better way to go about it that I can help you find that is supported.
