Cull Distance Volume - not working

I added Cull Distance Volume on the scene, pulled the entire map to fire distance for all objects inside. I decided that Size is 0, to take into account all the objects and the distance 4000. So, does not work correctly. Somehow, calculated from the center, some of the objects in the distance originally there, and when you approach to the OSI, then they disappear.
What’s wrong?

Hi,

You can use the information contained here for UE3/UDK that is still pretty accurate for how Cull Distance Volumes work with UE4.

UDK | VisibilityCulling Distance Volumes

There are some example settings listed towards the bottom of this section I linked that will help asl well. With Cull Distance Volumes make sure to use different size/distance levels.
