Set up Quest, SteamVR, and LIV. The latest steps and information can be found on our help desk guide. This process will change as we make improvements. It’s also best to test with a static camera rather than a dynamic camera, just for the reason it’s not as involved to set up. The differences between the static camera and dynamic camera would be due to tracking inconsistencies with the LIV App rather than SDK integration. If your are testing Passthrough:
  1. In LIV, on the Capture -> Manual page ensure that Effect is Dump + Presence Platform
  2. In LIV, on the Output that Hide Background is enabled
Top Left: Foreground RGB Top Right: Alpha If “Hide background” is enabled Foreground alpha (pink) & Background alpha (blue) Bottom Left: Background RGB Bottom Right: Composite What to look for, in addition to all the criteria covered in Basic Mixed Reality testing.
  • With Hide background enabled, all the elements in your game that you’ve specified to be hidden in Passthrough mode are black in the foreground, background, and Alpha quadrants.
  • In the bottom right composite, you’ll see the real life camera feed with the foreground. The background will not be visible in the composite.
  • If you’re testing with a default avatar camera, you should see the green LIV avatar being obstructed as different game objects go in front of the player. Vice versa, the default LIV avatar will block background objects.
  • For real cameras, LIV does not have a live segmentation (background removal) at this time. It’s best to use a green screen and go through calibration.
When verifying other Presence Platform capabilities like hand tracking, scene and anchors it is not necessary to use Dump + Presence Platform and enabling Hide background.
  • You may use the dump + composite
  • With hand tracking, you should verify that the virtual hands and avatar hands are lined up and the composite reflects in-headset movements
  • With scene and anchors, you should be seeing the composite respecting the anchors and scene you’ve set up with your game play
