Thanks for your suggestion. I tried out first bit (a plane below everything set at -2000 units Z):
Unfortunately though I couldn’t get “Simple Move to Location” to do anything. I logged hit value and equality to -2000 succeeded, but player pawn didn’t move. I suspect it’s because plane isn’t part of NavMesh.
I’ve been looking through Blueprint nodes and I can’t seem to find one that will pause pathfinding.
