No "Lock Viewport to Actor" In the Viewport Options?

Hi. I am watching UE4 tutorial, and there is a “Lock Viewport to Actor” option in the In the “Viewport Options”. But there’s no such option in my Viewport!
What’s wrong with UE and why it was deleted. How can I locate this option now?

Hi LetoDeath,

This was changed a few release back and is now located in the right-click context menu. It has also been renamed to “Piloting”.

You can read more about it and how to use it here in the documentation:

Thank you!
