Ah yep, that’s an important thing to note. The server won’t set a network update for a variable if it thinks it hasn’t changed. Normally things like health are just replicated instead of RepNotify and then your UI widget is likely reading the value each frame, so you’re not reliant on a notify coming in. For the video, I just used a notify for the sake of the text render component (though it also could have just set every frame).
