VStreamer Live Face Portal is a companion app for iOS that streams high quality facial expressions, mic audio, and head tracking wirelessly to VStreamer Live. It can even record FBX animations with audio for you animators out there!
This works great with the Virtual Expression Helmet (Vex Helmet), which is designed to reduce neck strain for long streams by placing the iPhone on the top of your head instead of in front of it.
This requires an iOS device with Face ID capability.
