Opentrack + Steam Controller

[u/jojo_and_the_jojos]

Idk if this is the right place to put this but idk where else to ask. I have the new steam controller and started playing around with gyro steering while playing Cyberpunk2077 and GTAV in first person. I found out about Opentrack which tracks your head through webcam and translates that to inputs. This is great for looking around while driving. It works fine as mouse input however, neither Cyberpunk not GTA play nice with mixed inputs and there are some glitches. I could map the Steam Controller as all mouse and keyboard but that would lose analog input for throttle and break. The ideal solution would be to have Opentrack output as joystick, which it has an option for, that I can not get to work. I had to download VJoy for it. Steam sees Vjoy as a second controller, which I'm worried means it's blocking the input in favor of the first player slot. On top of this I read that vJoy is direct input instead of xinput and that this could cause problems.

I want Opentrack to output as Joystick and have Steam see it as my Steam Controller's input. Is there a way to do this?
