# Testing LIV - Basic Mixed Reality

1. If using a Meta headset, ensure the runtime in SteamVR is set to SteamVR, not OpenXR ([How to set SteamVR as your OpenXR runtime](https://help.liv.tv/hc/en-us/articles/11607914857106-How-to-set-SteamVR-as-your-OpenXR-Runtime))
2. Make sure the game is playable before running with LIV. This step establishes a baseline that any impacts to the game could potentially be due to LIV and the LIV SteamVR Driver.
3. Start LIV & make sure LIV Output is running

Select Mixed Reality Capture, Start PCVR Mixed Reality Capture. Starting the capture will launch 2 windows; the compositor LIV Output window & the LIV Settings window

Select Camera -> Add (green camera with + sign) -> In the Type drop down menu select Video camera -> In the device drop down menu select your camera device here -> In the Resolution drop down menu select the resolution your camera is set to Note: If you are using Nvidia Broadcast make sure to scroll down and use ARGB -> Save

Run OBS capturing the LIV Output using game capture and also capture SteamVR VR View using game capture. We do this to record the output as an audit/history of changes.

4. Start game, once with Auto and another with Manual

Sync & Launch via the Auto tab in LIV Select the game in the drop down menu and select Sync & Launch. LIV does its best to automatically detect supported launched games on Steam and populate the dropdown.

Try launching the game separately, and manually target the game.exe with LIV through the “Manual” tab

5. Verify if any in-game options are present as some games have added controls to enable LIV.

Any launch issues (special options required, desktop window issues) - Help Guide Check menu options for graphics quality and mixed reality specific settings

6. Mixed Reality Capture checks

Viewing the compositor window LIV Output with Default Compositing effect selected, check objects and any in game UI for correct foreground behavior. Correct behavior will show the person in front or behind game objects, depending on the angles. Using OVR Advanced Settings to change angles is helpful at this point.

Check again in LIV’s dump + composite mode Effect mode for proper behavior. Dump + Composite mode shows the individual layers that make up the composition.

Check various angles by rotating play space with OVR Advanced Settings using the Rotate Space slider in the Offsets tab

Check Fake Lighting modes in LIV.

Check that the FoV override features behaves accurately

Calibration check, ensuring the virtual and real controllers are aligned and the latency of controllers are minimal.

[Check live re-calibrations](https://help.liv.tv/hc/en-us/articles/360016507779-Calibrating-Your-Camera) Do a quick *bad* calibration and see if it takes, you will be able to quickly tell by checking calibration in the LIV Output window.
