Hello, guys. I want to create a huge map and also have some navigable objects in the sky, but my navigation bounds only generate navigation in fixed height under it’s’ bottom. (~24.5k as I found by testing). Creating multiple bounds didn’t fix it.

How to generate navigation in all navigation area?
