NavMesh Slope

[HeroicVillain]

NavMesh doesn't currently generate past 89 degree slopes, preventing it from wrapping around a sphere. Not sure if you planned on adding path finding to your sphere worlds, but I think this is what's preventing it

I don't see the point of having navmesh for verticle planes.

To walk on spheres/terrain deformed past a certain slope

Thanks for the report! Sadly this seems to be an engine limitation, so I don't think it can be fixed easily.
According to this, it would require a custom A* implementation. Will try to do that one day.
