LTEK Gamepad to VRChat OSC

main.py

# You need to install the 'pygame' and 'pythonosc' libraries
# Since the LTEK is a gamepad, VRChat will read its button presses as game inputs which we do not want
# A solution to that is to use https://github.com/ViGEm/HidHide to hide the controller input to the VRChat process.
