Ah, level streaming could throw a wrench into things. I came across this thread. In it, it is suggested that the NavMesh Volume should be in the Persistent level.
I also just noticed a ‘RecastNavMesh’ actor that gets created with the BoundsVolume. Some promising settings on that like. ‘Force Rebuild on Load’ and “Runtime Generation”
I’m not sure what the grey nav mesh means…
Let me know if neither of those ideas help. Being able to use teleport navigation in a level loaded via level streaming is important!
