Empty Blocks Loading During Gameplay

I am seeing empty blocks as I walk around the map (map from the marketplace), how do I stop this?

Please see the attached video, the building at the back shows the issue.

The_Hivelord1, hello. Thank you for posting your question.

This sounds like its something to do with occlusion culling.
I tested the same pack you have and found that if I alter the value for bounds scale the concern is reduced.

I hope this helps.
