Make a NavMeshBoundsVolume.
Scale it a RIDICULOUS amount like 100000, you will see Building Navigation, if its over a million, guarantee the editor will hang because of crazy memory allocations.
The problem with this isn’t just “dont do that”, i had a navmeshvolume this ridiculously sized in a level, and I COULDN’T LOAD THE LEVEL because of Building Navigation (1000000) would hang it every time. And disabling ‘Auto Build Navigation’ in Editor Preferences doesnt prevent the initial build.
Hello rajkosto,
I was able to reproduce this issue on our end. I have written up a report ( UE-18266) and I have submitted it to the developers for further consideration. I will provide updates with any pertinent information as it becomes available. Thank you for your time and information.
Make it a great day
