Automatic patch tool to correct bad head tracking camera planes in Farming Simulator 19.

farmingSimulatorCameraFix.py

# Automatic patch tool to correct bad head tracking camera planes in Farming Simulator 19.
# The tool scans for X rotation values in indoor camera nodes in i3d files and sets them to 0.
#
# Change "rootPath" to your game install directory + "data\\vehicles"
#
# * Run with "python farmingSimulatorCameraFix.py patch"
# * Undo with "python farmingSimulatorCameraFix.py restore"
#
# Notes:
# * Doesn't fix mods - only original vehicles
# * Doesn't seem to work on some harvesters (TX32, maybe others) due to strange camera values.
#
# Written for Python 3 by Kizzard
