Spline player not fall down unreal engine 4

I have created the road using spline (roadBP) and i also set the path for my pawn player using spline (playerpathBP). My pawn is move forward on spline playerpath that is on the spline road using event tick . The problem is that if there is no road then the player is not fall down. because it is moving using spline. I want to make the pawn fall when there is no road.Player not falling down unreal engine - Programming & Scripting - Epic Developer Community Forums
