In this video, we'll show you how to use
a single iPhone or iPad to do Vtuber
live streaming in Werudo. We'll be using

Then select VMC for both face tracking
and pose tracking.
Click okay all the way through.
Select VMC receiver in the sidebar where
you can see [music] the listening port
and IP address. Next, in Sia, tap the
gear button in the bottom right corner
to open the settings dialogue and enter
the IP and port.
