An amazing user created a drag-and-drop system for being able to use your Oculus Rift CV1 Touch Controllers as Body Trackers. I got it up and running one day before the Security Update dropped, and now that it has, it detects I have an extra Driver in the SteamVR Folder, and Crashes the game when I try to join any other world than my Home. This is the most bullet-proof cheap tracking option, as an old Rift CV1 can be had for $120 used. I would be happy to supply the Driver Files if you would like to take a look into it, or at least allow it because it is not a modification of VRChat, merely adding an extra Driver to SteamVR to allow people access to affordable FBT.
Here is the Github Link for the Drivers: https://github.com/mm0zct/Oculus_Touch_Steam_Link
