# xrizer
- [xrizer Git repository](https://github.com/Supreeeme/xrizer)

> xrizer is a reimplementation of OpenVR on top of OpenXR. This enables you to run OpenVR games through any OpenXR runtime without running SteamVR.

{{% hint warning %}}
**Application developers**: The OpenVR implementation is incomplete and contains only what's necessary to run most games for compatibility and may omit certain information - if you plan to implement software, utilize the [OpenXR API](https://registry.khronos.org/OpenXR/specs/1.0/html/xrspec.html).

## Using full body trackers

{{% hint warning %}}
**This branch is a work-in-progress!** Unexpected problems may occur while in use, if you encounter issues while using this fork you should not report it upstream unless reproducible on the `main` branch of xrizer.

If you would like a battle-tested solution, see [OpenComposite](/docs/fossvr/opencomposite/).

Currently xrizer does not support full body tracking, however there is a **work-in-progress** [fork by RinLovesYou, maintained by Mr-Zero88](https://github.com/Mr-Zero88-FBT/xrizer/tree/experimental2) with support while using Monado.

To use the above fork, follow these steps:

### Envision
- Click the three dots next to the profile selector and select 'Edit profile'
- If a popup asks if you would like to duplicate the profile, click yes.
- Scroll down to 'OpenVR Compatibility' and set the following fields:
  - OpenVR Compatibility Repo: `https://github.com/Mr-Zero88-FBT/xrizer.git`
  - OpenVR Compatibility Branch: `experimental2`
- Clean build your profile from the menu at the top right, or use the Ctrl+F5 keybind.

### NixOS
Apply an overlay over nixpkgs to override the xrizer src:

```nix
{
  nixpkgs.overlays = [
    (final: prev: {
      xrizer = prev.xrizer.overrideAttrs {
        src = final.fetchFromGitHub {
          owner = "Mr-Zero88-FBT";
          repo = "xrizer";
          # IMPORTANT: Fill the below field with the latest commit hash from https://github.com/Mr-Zero88-FBT/xrizer/commits/experimental2 (click the Copy full SHA button on the right side)
          rev = "";
          # IMPORTANT: Replace the below field with the correct hash, the error when building with this empty will give you the expected hash.
          hash = "";
        };
      };
    })
  ];
}
```

## Rebinding controls
The process is mostly the same as [OpenComposite](/docs/fossvr/opencomposite/#rebinding-controls), but replace the `OpenComposite` directory name with `xrizer`.
