Thanks. 50% it seems not much but I guess it was much smaller before 🙂
In order to move in VRChat you can use only ps moves. you click ps move button and move it where you would expect trackpad to be. You can test it in SteamVR before game. There are also options in Device Configuration / PS Move Tab / Configuraiton.
You can set there to reset trackpad position to center each time it is unpressed.
This was working very well for me although when you look at this first does not seem to be.
So your plan is to set up ps navi on the top of ps moves like in psmoveservice ?
