Sound

Blocked players

Blocking hides their chat and their character, so their name disappears and you can't click it to undo. Unblock them here.

Voice chat

Push to talk (hold V) Always on (sends when you speak) Voice volume Mic sensitivity: talk, and drag the handle to where your voice should start counting

Turn the mic on (🎤, bottom left) to see your level here.

Use headphones so others don't hear themselves. Mute a player with 👥 next to the mic button, or by clicking their name in chat.

Camera

Camera follows my character (Shift+C)
