Hi! For a cave environment, I need to run Unreal in game mode (packaged or via -game argument), and I have been struggling to get LiveLink to run outside of editor. Documentation mentions “UDP Messaging is not enabled by default in game. You can enable it by adding messaging in a packaged game”. …

For anyone else got this livelink doesn’t receive data issue. YOU JUST NEED CLOSE EDITOR. and run game alone. Don’t do anything more complicated, you don’t need blueprint, this just can work.
