It appears the HealthDisplayType property of Humanoid (the property which allows you to see the health bar of things) only works when there is a part named “Head” in the humanoid’s parent. Not only is this not documented in it’s wiki page (Humanoid | Documentation - Roblox Creator Hub), but it is also buggy.
Description: When there exists a group of parts with a humanoid who’s HealthDisplayType is set to anything which allows it to be viewable in Studio (i.e. AlwaysOn or DisplayWhenDamaged), and a part is inserted into the model, and the part is renamed to “Head”, the humanoid’s health bar will be displayed above said part. However, upon renaming this part to anything - say “2”, and renaming back to it’s original name - “Head”, the health display can no longer be seen in the Studio editor, however it can be seen during “Run” mode. Likewise, if there already existed a part called “Head”, and said part was renamed, and named back to “Head”, the health bar fails to be displayed above the part. In addition, the character’s name fails to be displayed also. It should be noted that upon restarting studio, the health and name display both show up, however after the process is replicated, the bug once again happens and the health and name display both disappear.
