I’m currently working on a project were I made a road using the splines on the terrain and then adding a static mesh to the splines to make it visible and working in the game. All I basically need right now is to add level bounds or blocking volumes so you cannot go outside the road and I was wondering if there is any way to easily add level bounds or blocking volumes to the spline meshes and/or the static mesh instead of doing everything manually using geometry editing and blocking volumes? Basically doing everything manually works but takes alot of time, so if the option to “quick add” something like this I would love response 
Thank you in advance,
