Hi,
Couple of things to check and make sure.
- Make sure that Project Settings DOES NOT have static lighting disabled. Precomputed Lighting is required for Precomputed Visibility Cells to be placed.
- Also I don’t believe that “Hollow” volumes are supported. Even if it was, the setup the you have would not render any visibility cells because the outer ringed area has no shadow casting surfaces to be placed on. If your goal is to have them in the building where visibility culling matters most then you need to scale down this cylinder and turn off the hollow setting.
I hope that helps get your sorted.
