I didn’t realize you needed the player controller in the scene. Thank you!
EDIT: Unfortunately even with the player controller in the birds wont seem to land for me. Also the test scene i used did have a player controller in it since it was the default “blank” UE4 map.
Maybe the logic doesn’t work in simulation for some reason?
EDIT2: Here’s the behavior I’m seeing in StayOnGround_Birds.umap that comes with the package. All birds instantly fly away indefinitely.
