Welcome to the LIV Wiki!

This wiki is under construction! If you would like to help please create an account and participate in creating some pages! Let us know on our Discord if you are so we can put you in the credits, and distribute virtual hugs : )

Massive thanks to Ragesaq (https://twitch.tv/ragesaq) for setting up the Wiki server for us. You're a rockstar.

About LIV

LIV is a windows app available on Steam for creating Mixed Reality in VR using the openVR API. It is currently officially supported on the HTC VIVE and Oculus Rift using SteamVR. Windows Mixed Reality support is forthcoming.

LIV is still in Early Access, and we're working diligently in improving stability and performance across all devices and hardware configurations. We're still a small team of nerds who are working on this because we absolutely love what we do, and want to empower more people in VR to create compelling VR content. In other words, LIV is the result of Ikigai from everyone involved, including you fine folks in our community.

Thank you for all your continued support!

Creating Mixed Reality with LIV

Required Hardware


Oculus Rift or HTC VIVE
VR Ready PC with

  • GPU: Nvidia 1070 or higher
  • CPU: AMD Ryzen/Intel i7 or better
  • Webcamera or DSLR camera
  • Optional: Capture card (needed if you are not using a webcam)
  • Greenscreen
  • Update! We're beta testing green-screen less background removal using the Kinect V2. Hop into our Discord and sign up for the beta in the #no-green-screen channel.


Incompatible Hardware


The following hardware does currently NOT work with LIV:

  • AMD Radeon GPU's
  • Blackmagic capture cards

Required Software


Download the LIV Client on Steam

LIV is the app that will handle the compositing for you!

Download LIV:VIVR on Steam

LIV:VIVR is the calibration tool that helps you calibrate your virtual camera!
Note: It will be integrated into LIV soon.

OpenVR Advanced Settings Plugin
The OpenVR Advance Settings plug-in can be used to rotate/zoom in-out your playspace, allowing you to get a good camera angle.
This is also very useful if you are preparing non-live content with a static camera or need to get the correct angle for a live stream.

Recommended Cameras


Generally speaking, any camera that is picked up as a Webcamera should do the trick.

Cameras that our users have confirmed work with LIV.

Webcameras

  • Logitech C920
  • Logitech C922
  • Logitech C930e
  • Logitech Brio


Action cams and DSLR’s (these require a capture card, read more in the Recommended Capture Card section.

  • GoPro Hero 5
  • GoPro Hero 6
  • Panasonic G7
  • Canon 6D
  • Canon 550d
  • Panasonic GH5


You're welcome to try other cameras and report back on compatibility.

Recommended Capture Cards


Generally speaking, any low latency card from Avermedia or Elgato should work. Capture cards that our users have confirmed work well with LIV:

  • Avermedia LGX
  • Avermedia Extremecap U3
  • Elgato HD60 Pro
  • Elgato 4K
  • Avermedia Live Gamer HD2

Setting Up An Effective Green Screen


Big thanks to VRJosh (https://twitch.tv/vrjosh) for putting this segment together!

Key Points:

  • Remove all wrinkles/folds from your greenscreen, remove as many shadows as possible.
  • If using multiple greenscreens, cover any seams with green gaffer tape
  • Ensure you have lots of static light, preferably from multiple diffused light sources
  • If possible have your greenscreen set in an interior room with as little ambient/outdoor light as possible.


The primary concern when setting up a greenscreen is to provide a smooth, uniform surface in the background of your shot. This means trying to get rid of any wrinkles or seams in the greenscreen as these create shadows which are harder to key out.

The easiest way to create a smooth greenscreen is to hang a single screen from a supporting beam and let gravity pull it straight. However, to get a wider mixed reality shot you may wish to cover another wall and the floor with greenscreens.

This might require you to use 2 or more screens, in which case you’ll want to use some green gaffer tape to cover the seams.

In addition to the screens themselves, the other most important factor is lighting. To get a smooth background image you’ll want to preferably use at least 2 strong light sources with diffusion filters. This will spread out the light evenly and prevent your own shadow from potentially interfering with the chromakeying.

Another important thing to consider is where in your house/office to place your greenscreen set. Rooms with exterior windows, particularly windows that receive direct sunlight, are going to provide extra challenges due to the ambient lighting changing throughout the day which may change the apparent color of the greenscreen.

If you must place your set in a room with a window, you may want to place some extra dark window coverings over it (unless you’re doing all your recording/streaming at night).

You can get most of the required equipment of places like Amazon or your local hardware store. If you are looking for a higher end, professional solution, LIV also sells the LIV Cube.

How to Broadcast and/or record Mixed Reality


You can record and stream with software like OBS, Xsplit and Shadowplay, and there are many more options for you to explore.
We’ll go over OBS setup as it’s the most commonly used.

OBS Setup


Game Capture

  • Add a new Game Capture Source to your OBS Source List.
  • Select capture.exe as your Game Capture Source.


Window Capture

  • Add a new Window Capture Source to your OBS Source List.
  • Select the window you want to target in your window list.


LIV OBS Plugin

To install:

  • Right-click LIV in your Steam library, and click “Properties”
  • Click the “Local Files” tab
  • Click “Browse Local Files…”
  • Go into the “resources” folder, then “OBS”
  • Next, you’ll want to open a new File Explorer window, and navigate to where you installed OBS. This is usually in “C:\Program Files (x86)\obs-studio\”
  • Go into the “obs-plugins” folder, then “64bit”
  • Copy the “obs-liv-capture.dll” from the first folder into the plugins folder


Once you’ve got your game feed into OBS/Xsplit, it’s business as usual. You can add your own overlays, play around with your encoding settings and get your stream going!

Make sure you share your LIV streams to our #live-with-liv channel on Discord -- our community would love to see it!
