Virtual Keyboard as a feature is being deprecated in favor of the system keyboard overlay in Unity.
Please see System Keyboard Overlay for instructions on enabling the system keyboard as an overlay in Unity.
Q: How do I use both the system keyboard and virtual keyboard? A: Disable the system keyboard for input fields you want to use with the virtual keyboard. For Unity input fields, this can be done using < inputField >.keyboardType = (TouchScreenKeyboardType)(-1); in a script.
Q: Why is the keyboard not visible? A: Make sure Virtual Keyboard and Render Model are enabled in OVRManager. If they are and you still do not see a keyboard, navigate to Project Settings > Meta XR and fix any reported issues. Your headset must also be v54 and above.
