By default, there is no attribute of SteeringAngle inside GameData inside Properties.
However, with RomainRob's software RCS, I am able to have introduced two new variables for Steering called 'ExtraInputProperties.SteeringAngle' and 'ExtraInputProperties.SteeringHalfRange'. Unfortunately, none of those two variables respond to any Steering all while 'DataCorePlugin.GameData.Throttle' or 'ExtraInputProperties.Throttle' do.
I have tried creating a Dashboard that contains those variables as well as used a pre-made Overlay that contains all those. It's as if it's not detecting my amount of steering.
I'm playing on PS4 with a Thrustmaster T248 with my wheel connected to the Playstation.
Some have suggested to find a way to receive input directly from the wheel connected to the PC and then using the 'Joystick' variable, but obviously you can't control your Playstation from your wheel connected to the PC, even via Playstation Remote Play.
If somebody can find a way to show steering wheel angle in Gran Turismo 7 it would be awesome!
Like they do in the Gran Turismo World Tournament when you watch it in Dynamic Viewing.
