Question How to work HideFlags.HideAndDontSave

i have a lot of objects in the scene that i sometimes move, sometimes i need to move an object that has a lot of child objects but they are turned off, but even in the off state it affects performance, is there any point in hiding objects using HideAndDontSave to increase performance?

that is, the essence is this - I need to move an object that has an animator (in which there are many child objects), if the object is outside the screen, then the animator turns off, but it is still attached to the moving object, but what if we hide it?
or how can it be disconnected for a while and quickly returned as needed?

 

HideFlags is an entire only thing, despite it living in the UnityEngine namespace.

 

does using these flags affect performance?

 

Well as it says in the docs:

So, potentially? You'd have to profile it, but it really only serves a purpose in the editor. It's not a runtime tool.

The animator component already has a built in options to cull it when it's not being rendered, so I think this exercise is pointless.

Again, profile, find the true cause of your performance issue, and find a focused solution for it.
