Issue: "Visor + Vivecraft used together"

It can cause different problems, most common is broken height, you can be 4 meters while hands are normal.

Solution: Use only Visor or Vivecraft, not both

Issue: "VR runtime not detected"

Symptoms

In latest.log you see an error: ERROR_FORM_FACTOR_UNAVAILABLE - it means no VR runtime or headset detected

What are the causes and solutions:

1) OpenXR support not enabled on SteamVR

2) SteamVR Not Detecting Headset unless steam ran as admin (Error 108)

To fix: The most obvious solution is to run steam as admin.

But for those who want a complete fix on Windows:

  • Open Local Security Policy (If you don't have this or have Windows 11/10 home. You can download the Windows 10 Version here. You can open this via Run and typing in "secpol.msc"
  • Select the dropdown arrow on Local Polices
  • Open Security Options
  • Scroll down to the bottom until you find something named "User Account Control: Run all administrators in Admin Approval Mode"
  • Double Click on it then disable it.
  • Restart PC.
  • After this is done, restart your pc and uninstall SteamVR and Reinstall it.

3) In other cases - VR runtime or headset just not recognized / not found

Issue: "The game is displayed on your desktop, but not in the headset"

This usually happens on systems with dual GPUs such as gaming laptops.

If your PC only has an Intel integrated GPU, then you won't be able to play Visor (VR + OpenGL don't like intel)

Solution For Windows users:

You need to force your PC to use gaming GPU for java application

First, determine which Java executable is being used, the path may depend on launcher and mc version you are playing.

  • Launch Visor you want to want to play on
  • Open the windows Task Manager by right clicking the start button, or with CTRL+ALT+DELETE
  • On the Processes Tab, right-click on “OpenJDK Platform binary” (or “Java(TM) Platform SE binary” for older versions) and choose ‘Open File Location’
  • The location of the running java executable will open. Copy or save the path to this folder.

Secondly, set Windows to use the correct GPU

  • Open the Settings App
  • Go to Graphics Settings
  • Select Desktop App and then Browse
  • Browse to the folder, or paste the path in the navigation bar
  • Select javaw.exe and click Add
  • Expand the newly-added entry in the list and click Options
  • Select ‘High Performance’ and click save

You might need to repeat this process for different mc versions, launchers

If problem is not resolved:

  • Ensure you Headset is connected with PC (or plugged into dedicated GPU)
  • If you are playing through SteamVR, make sure you configured it properly. (OpenXR supported)
  • Ensure you actually have a dedicated GPU (not only Intel)

Solution For Linux users:
