Inspector questions(lock,static).

I want to know about some function in inspector,
I found “static” and “lock” function in inspector ,but ,I don’t know how or
when to use it?(I found document but I really don’t understand it)

In Unity you can have multiple Inspector tabs. If you click on an object in the Hierarchy it will open in both inspectors. If you want to look at the difference between 2 objects. You can lock an object, then that inspector won’t change. then you choose another object which will open in the other inspector. You can see the difference and change it if you want.

Static is used when you want Occlusion Culling.
