I'm using a Valve Index and when I open the game, I have no hands and the menu doesn't open. Might be some bugs in there that prevent the index bindings from working :(
I'm gonna quote my reply to another message:
Are you able to test with the Meta Quest Link app (Oculus Home) installed on your PC? No need to login/setup or anything, just the app installed.
I have a feeling, even though you're not using a quest headset, that my game might have a dependency on it... (it was developed using their XR SDK)
That would really help if you were able to try, as depending on the result I might need to pull the windows version temporarily to recode it with Unity's XR SDK. I don't want people to pay for something they either can't play or force them to have meta software installed.
I do have the app installed yeah, I used to have a Rift S myself. I tried switching between OpenXR and SteamVR runtimes and OpenXR prevented the game from even working (similar issue to someone else's comment I believe). I even tried disabling any plugins or add-ons in SteamVR too, nothing worked there. So you'll likely have to recode the game using Unity's SDK.
