NAV mesh generating in the air.

Hey UE4 community!

I am working on a Hospital for VR but My nav mesh is not working how it is supposed to be.
It spawns in the air but there are no collisions there. I tried restarting UE4 But that did not help.

do you know a solution to this problem?

Do you have any volumes in your scene? There could be some collisions applied to them which could cause this.

Try go into collision mode in your editor and see what it could be colliding with.

Is there any location assignments in the blueprints? Specifically if there’s any location assignments on the on tick loop. I was getting what appeared to be collision displacements that were actually a result of different components in the same blueprint not being assigned to location properly.
