I want to use different HLOD methods depending on the assets.

For large objects like buildings made up of instances, I would like them to be in a simplified polygon state. For other smaller objects, it would be ideal if they disappeared. However, when I set it to ‘approximated’ and build HLOD, the opposite happens. Large buildings disappear based on distance, and smaller ones are left as simplified meshes.

There is an HLOD Layer item in World Settings, and there is also an HLOD item in asset details. Do I need to separately specify the HLOD item for each asset?
However, it doesn’t work as intended, perhaps due to the HLOD Layer in World Settings.

How is HLOD Layer typically set up?
