Planet Navmesh For AI

Just curious if anyone has come across a solution for generating a navmesh on a spherical world. I know that UE4 can generate navmeshes dynamically during runtime for large worlds, why couldn’t it generate them based on the the pawn up vector instead of global z? The navigation invoker in the ai pawn could pass the correct vector and the nav mesh could be based of that. I just have no clue how to implement that lol. If anyone has seen anything kicking around, I would love to hear about it.

Also I have tried DoN’s 3d pathfinding, but it leaves a lot to be desired with grounded npcs, as they try to fly up over obstacles instead of knowing to go around them.
