From the talented peeps at Normal VR:
“If you haven’t heard of Normcore yet, it’s a multiplayer networking plugin that we created at Normal. Normcore allows you to easily add avatars and voice chat to any Unity VR/AR app in addition to any other multiplayer networking you might need.
If you’ve got a prototype that you’d like to share with someone, just import Normcore, add the “Realtime + VR Player” prefab to the scene, and you’re done. When your app opens up, it will automatically connect everyone to the same room, and spawn simple avatars with working voice chat.”
