Some Questions about useful function I need

[UsernameHed]

Hello , Again a little Question / suggestion:
We can't go backward by setting the speed to negative with the SplineController.
So as the commentary suggested, I can set the Direction to BackWard... But then my car rotate, and I don't want my object to rotate, I just want to go backward xD

So maybe I can set every Update the RelativePosition to (_splineController.RelativePosition - amountSpeedBackward), but how do you calculate the amountSpeedBackward ?

Or maybe you already have an option for this ?
Thanks
