Tomcat DaveTheCoder Actually, the tutorial says to use a VisibleOnScreenNotifier3D, not a VisibleOnScreenEnabler3D. This is not in the originally submitted piece of code at all. I guess it didn't get to that point then.
DaveTheCoder The .zip has a VisibleOnScreenEnabler3D node in the Mob scene, with visible turned off. It didn't occur to me that was a problem, until spaceyjase figured it out.
Tomcat EFrion Here it is! You put the mob scene in the main scene for some reason. This is not in the tutorial. I would suggest that you start doing the lesson from the beginning, following the tutorial exactly and with extra attention to detail.
DaveTheCoder I'll post the issue here for reference: Add warning in editor when visibility screen notifier's is disabled #8123
