vr across paltform

so im pretty new to developing at all and im trying to make a vr game. i only have a wmr headset so thats the platform i use to develop the game. will that game be playable on vive and index as they have the same inputs (that being trigger grip touchpad and joystick)?

As far as I know, the only VR plugin that has compatibility across multiple categories of VR devices is the SteamVR plugin SteamVR Plugin | Integration | Unity Asset Store

The Windows MR platform should only work for WMR devices, which doesn’t include the Vive or the Index Unity - Manual: VR development in Unity
