Now that you've (hopefully) got your avatar all sorted, it's time to open up the LIV in-VR avatar interface.
1. While wearing your HMD, look down towards the floor and you'll see a LIV icon.
2. You can access the avatar interface by pointing your controller and hovering the green dot over the LIV icon until it fills up in green. You do the same to exit out of the interface.
Here you will find all your avatar and virtual camera settings, all controllable from within VR.
