it would allow players to communicate with other players when i say this i don`t mean live you can take recroom for example there is a system that allows you to record your in game audio. To allow players to hear it their would be a audio block ,in the selection tab you can control the volume the speed and allow it to loop
we already have a camera for thumbnails but it would be helpful if we could also you it as a video camera for youtuber/streamers it would help grow the game and give a little more creativity, just like the audio block it would show what was recorded and the audio in it. In the settings you can access volume control the speed and make it loop.
