Splines tools in static mesh

Hi, i build my stage, so, my track is a static mesh, but i want to create a barricade using a spline tools, but i see can only use with landscape, no like foliage, you can use foliage in everthing, any solution?

You can simply move the control points upwards to where the barricade should be - completely off the terrain.

We should have splines independent from landscapes sometime in the future, but for now you can try using blueprints for that. You can find some samples in Content Examples project > Blueprints_Advanced.
