How to set up precomputed visibility

Hi guys!

I am trying to find information on Precomputed Visibility.

I am having trouble finding information about it. I have it turned on in my level and I do have a PrecomputedVisibility Volume in the level.

How do I see the cells?

Is there a way that I can tell if it is working.

I will mention that this is a mobile game being made for iOS and Android.

Here is another very bad question. That is, what is Culling? Is PrecomputedVisibility a form of Culling?

I am trying to figure out how to optimize my scene with PrecomputedVisibility as much as possible but I can not seem to find much information about it.

I literally can not find much at all about this. Is it not used that much any more?

Any links that any of you are aware of would be much appreciated. Thank you in advance
