Installation
Set the Head motion to 0% in the Menu Control settings.
First, edit the file\rFactor\UserData\player\player.PLR
And change those lines like this
Cockpit Vibration Mult1="0.00000" // Primary vibration multiplier affects eyepoint position (base magnitude is in VEH or cockpit file)
Cockpit Vibration Freq1="0.00000" // Primary rate of vibration affects eyepoint position (higher framerates allow higher rates)
Cockpit Vibration Mult2="0.00000" // Secondary vibration multiplier affects eyepoint orientation (base magnitude is in VEH or cockpit file)
Cockpit Vibration Freq2="0.00000" // Secondary rate of vibration affects eyepoint orientation
Car Vibration Mult1="0.00000" // Vibration multiplier affects cameras attached directly to the car
So the internal rFactor camera vibration will not interfere
Then set the max pitch/roll as default =>
Look Up/Down Angle="0.40000" // Angle to look up/down (pitch) w/ controller in radians (= degrees / 57)
Leanahead Angle="0.00000" // Angle to lean head (roll) w/ steering in radians (= degrees / 57)
Look Roll Angle="0.75000" // Angle to lean head (roll) w/ controller in radians (= degrees / 57)
Then copy RealHeadMotion.dll in \rFactor\Plugins
Now it's ok :)
Configuration File
It must be in same directory than the DLL file.
Default commented .ini in ZIP archive.
